NEW QUESTION # 124
Which OSPF packet type is sent when an OSPF router detects its database is stale?
Answer: D
NEW QUESTION # 125
You are establishing a new BGP session to an EBGP peer using loopback addresses.
In addition to your general EBGP settings, which BGP feature must be enabled for this session to establish?
Answer: B
Explanation:
By default, EBGP sessions are built with the expectation that peers are directly connected at Layer 3, and Junos enforces this by sending EBGP packets with a TTL of 1. When loopback addresses are used as the session endpoints instead of the directly connected physical interface addresses, the resulting IP packets must traverse at least one additional router hop between the two loopbacks, and a TTL of 1 will expire in transit before reaching the remote loopback, causing the TCP handshake - and therefore the BGP session - to fail even though a valid route to the peer's loopback exists. The multihop statement (configured as an EBGP multihop parameter with an accompanying TTL value, most commonly set to 2 for a single intermediate hop) instructs Junos to increase the TTL used for that peer's BGP packets so they survive the extra hop count between loopbacks. This is a mandatory addition any time an EBGP session is deliberately built against non- directly-connected addresses, whereas IBGP sessions, by contrast, do not have this default restriction because IBGP already assumes peers may be multiple hops apart within the same AS. Multipath affects load-balancing across equal-cost paths, damping suppresses flapping routes, and passive controls whether a router waits for the remote peer to initiate the TCP connection - none of these resolve the TTL expiration problem inherent to loopback-based EBGP peering. Reference topics: Junos Enterprise Routing - BGP, Configuring EBGP Multihop Sessions.
NEW QUESTION # 126
Which sequence correctly describes the basic message flow that leads to a successful BGP peering session?
Answer: A
Explanation:
RFC 4271 defines the BGP finite state machine as a strict, ordered progression of six states that a session must move through to successfully establish. A newly configured or reset session always begins in Idle, where BGP initializes resources and refuses connections until the ConnectRetry timer fires. From Idle, the router transitions to Connect and attempts to establish the underlying TCP transport session to the configured peer address on port 179. If that TCP attempt does not immediately succeed, the session falls back to the Active state, where the router continues retrying the TCP connection in the background; once the TCP handshake finally completes (from either Connect or Active), the session advances to OpenSent, during which the router transmits its own BGP OPEN message advertising its AS number, hold time, BGP identifier, and capabilities. Upon receiving and validating a compatible OPEN message from the peer, the session moves to OpenConfirm, where both sides exchange KEEPALIVE messages to confirm the parameters negotiated in the OPEN exchange are mutually acceptable. Only after this confirmation does the session reach Established, the final state in which UPDATE messages carrying actual routing information begin to flow between the peers. Any deviation from this Idle Connect -> Active -> OpenSent -> OpenConfirm Established ordering, as presented in the other answer choices, does not reflect the standardized BGP state machine.
NEW QUESTION # 127
You have configured a GRE tunnel from your local router with tunnel source 10.0.0.1 to a remote router at destination 192.168.0.1. The tunnel is functioning until you commit set routing-options static route 0.0.0.0/0 next-hop gr-0/0/0. This configuration causes the tunnel to go down. Which statement is correct in this scenario?
Answer: D
Explanation:
A GRE tunnel's outer, delivery-layer packets are forwarded using the router's ordinary underlay routing table, meaning the tunnel destination address (192.168.0.1 in this case) must itself be resolvable to a physical, non-tunnel next hop for the encapsulated packets to actually leave the router. Before this configuration change, the default route (or some more specific route) presumably pointed toward a real physical next hop, allowing the router to reach 192.168.0.1 and keep the tunnel operational. When the administrator commits a static default route of 0.0.0.0/0 with a next hop of gr-0/0/0, every destination lookup that previously fell back to the default route -- including the lookup for the tunnel's own destination address, 192.168.0.1, since no more specific route exists for it -- now recurses through the GRE interface itself. This creates a circular dependency: the router needs to route to 192.168.0.1 to keep the tunnel up, but the only route it has to reach 192.168.0.1 now points back into the tunnel that requires 192.168.0.1 to already be reachable, so the interface's next-hop resolution fails and the tunnel drops. This is an entirely valid and common GRE design pitfall rather than any platform restriction; GRE interfaces can be legitimately used as static route next hops, do not require loopback-sourced encapsulation, and do not require a /32 host route to resolve their destination, provided that route does not recursively point back through the tunnel.
NEW QUESTION # 128
On Juniper devices, which statement correctly describes a basic characteristic of a GRE tunnel?
Answer: D
Explanation:
GRE is fundamentally a stateless encapsulation protocol: the encapsulating router simply wraps the passenger packet in a GRE header and an outer delivery IP header and forwards it based on ordinary IP routing table lookups toward the configured tunnel destination address. For that forwarding to succeed, the underlying (global or routing-instance) routing table on each endpoint must contain a valid, reachable route to the far-end tunnel address; without such a route, the tunnel interface will not come up or will be unable to deliver traffic, since GRE relies entirely on the existing IP infrastructure rather than any tunnel-specific signaling to establish reachability. Because GRE has no built-in state machine or session negotiation, it does not natively track whether the remote endpoint is alive - that requires an optional add-on such as GRE keepalives or BFD, neither of which is enabled by default; an operator must explicitly configure them if failure detection is required. GRE is also protocol-agnostic rather than IPv4-only: it can encapsulate IPv4, IPv6, MPLS, and other network-layer protocols as the passenger, which is one of its defining advantages over IP-in-IP tunneling.
Finally, because GRE keeps no per-session state about the peer, it cannot detect or report tunnel failures on its own, reinforcing why route reachability is the one true prerequisite for tunnel operation. Reference topics:
