Question Image

An MPLS LSP to 192.168.100.3 has been configured, but the LSP is down.

Referring to the exhibit, which two actions would resolve this issue?

Choose two
  • A Issue the set protocols ospf traffic-engineering command and commit.
  • B Issue the set interfaces lo0 family mpls command on router R1 and commit.
  • C Issue the set protocols mpls label-switched-path to-r3 no-cspf command and commit.
  • D Issue the set routing-options rib inet.3 static route 192.168.100.1 command and commit.
Explanation

CSPF requires a traffic-engineering database, which OSPF populates only when OSPF traffic engineering is enabled. Enabling protocols ospf traffic-engineering therefore allows the default CSPF computation to find the LSP path. As an alternative, no-cspf disables constrained-path computation, allowing the LSP to use the existing IGP route to the egress address.
