Referring to the exhibit, which LDP Layer 2 circuit configuration on PE1 maps traffic to an LSP destined to the
secondary loopback address of PE2?
A.
[edit protocols l2circuit]
user@PE1# show
neighbor 10.10.10.2 {
interface ge-1/1/1.1 {
psn-tunnel-endpoint 10.10.10.1;
virtual-circuit-id 1;
encapsulation-type ethernet-vlan;}
}
B.
[edit protocols l2circuit]
user@PE1# show
neighbor 10.10.10.2 {
interface ge-1/1/1.1 {
virtual-circuit-id 1;
encapsulation-type ethernet-vlan;
}
}
C.
[edit protocols l2circuit]
user@PE1# show
neighbor 10.10.10.2 {
interface ge-1/1/1.1 {
psn-tunnel-endpoint 10.10.10.2;
virtual-circuit-id 1;
encapsulation-type ethernet-vlan;
}
}
D.
[edit protocols l2circuit]
user@PE1# show

“neighbor” designates the PE router
The “PSN tunnel endpoint” address is the destination address for the LSP on the remote router.
By default, the PSN tunnel endpoint for a Layer 2 circuit is identical to the neighbor address, which is also the same as the LDP neighbor address.
