問題 #62
You are a network architect designing a brand new network. You want to deploy RSVP LSPs in this network. You are currently in the process of choosing whether to run OSPF or IS-IS as your interior gateway protocol.
In this scenario, which two statements are correct about IGP traffic engineering extensions in an RSVP network? (Choose two.)
答案：B,C
解題說明：
When using IS-IS in an RSVP traffic engineering environment, traffic engineering extensions must be explicitly enabled so that IS-IS advertises TE information such as link bandwidth and administrative groups to build the traffic engineering database.
When using OSPF, traffic engineering extensions must also be explicitly configured. Enabling OSPF traffic engineering allows the protocol to advertise TE attributes required by RSVP-TE and CSPF for calculating constrained paths.
問題 #63
Click the Exhibit button.
In the exhibit, Site A is sending traffic to Site B. R1 adds MPLS label 7166 to direct the traffic to R5.
Which two criteria did R1 use to determine which label number to add to the traffic? (Choose two.)
答案：B,D
解題說明：
R1 selects the label based on the packet's destination prefix (the FEC) and then uses the label that its next-hop LSR (R2) advertised for that FEC. In MPLS, each hop forwards using the downstream-assigned label learned from the immediate neighbor, not a label learned directly from the egress router.
問題 #64
Exhibit:
You have configured an MPLS LSP to 192.168.100.3. However, the LSP is in the down state. Referring to the exhibit, which two actions would solve this problem? (Choose two.)
答案：B,D
解題說明：
In a Juniper Networks environment, establishing a functionalMultiprotocol Label Switching (MPLS)Label- Switched Path (LSP) requires synchronized control plane operations. According to Juniper technical documentation, the most common reason for an LSP to remain in the "Down" state at the ingress router is a failure of theConstrained Shortest Path First (CSPF)algorithm during the path computation phase.
The provided exhibit for routerR1reveals a critical error in the show mpls lsp detail output: "CSPF: could not determine self". This specific error indicates that the CSPF process is unable to find its own local router ID within theTraffic Engineering Database (TED). For CSPF to build a valid TED, the underlying Interior Gateway Protocol (IGP), such as OSPF, must be configured to flood opaque link-state advertisements (Type
10 LSAs) that carry traffic engineering attributes. As seen in the OSPF configuration, traffic engineering is not enabled. Therefore, issuing theset protocols ospf traffic-engineeringcommand (Option D) will allow R1 to populate the TED with its own local information and that of its neighbors, enabling CSPF to calculate a valid path.
Alternatively, an administrator can choose to bypass the requirement for a TED entirely by disabling CSPF on the specific LSP. By issuing theset protocols mpls label-switched-path to-r3 no-cspfcommand (Option B), the router will stop attempting to perform a constrained path calculation. Instead, the signaling protocol (RSVP) will rely on the standardinet.0routing table to determine the hop-by-hop path to the egress destination (192.168.100.3), allowing the LSP to establish without traffic engineering constraints.
Regarding the other options, whilefamily mplsis required on all transit interfaces, the ingress loopback interface (lo0) generally does not require it for standard LSP signaling unless it's used as a transit hop.
Furthermore, adding a static route toinet.3(Option A) is used for next-hop resolution of BGP routes over LSPs but does not assist in the signaling or establishment of the LSP itself.
問題 #65
You are monitoring OSPF on a router and notice frequent state changes between Full and Down. Which condition would cause this behavior?
答案：B
解題說明：
When troubleshooting OSPF in a service provider environment, distinguishing between "stuck" adjacencies and "flapping" adjacencies is the first step. A session that transitions frequently betweenFullandDown indicates that the relationship can be established successfully (meaning parameters match), but it cannot be maintained.
According to Juniper Networks documentation, the most common cause for a session to drop from Full to Down is the expiration of theDead Interval. If a router does not receive a Hello packet within the Dead Interval (usually 40 seconds), it tears down the adjacency. Aphysical interface flapping (Option A)is the primary trigger for this. If the physical link or the underlying transport (like a leased line or a microwave link) goes down even momentarily, the OSPF process immediately detects the interface failure, flushes the neighbors, and moves the state to Down. As soon as the interface comes back up, the routers perform the Hello exchange and reach the Full state again, creating the flapping cycle.
Analysis of other options:
* MTU Mismatch (Option D):This typically causes the adjacency to get "stuck" in theExchangeor ExStartstate. The routers can exchange small Hello packets, but when they try to send larger Database Description (DBD) packets that exceed the MTU, the packets are dropped, preventing the session from ever reaching "Full."
* Area ID Mismatch (Option C):This prevents the adjacency from even reaching theInitstate; the routers will never form a neighbor relationship.
* Route Preference (Option B):This affects which route is chosen for the forwarding table but has no impact on the OSPF neighbor state machine itself.
