Configure the backup neighbor by including the backup-neighbor statement and
specifying the IPv4 address of the backup hub PE router. Router PE3 is the backup
neighbor in this example. Also include the standby statement at the [edit protocols
l2circuit neighbor 192.0.2.5 interface ge-1/0/0.0 backup-neighbor 192.0.2.3] hierarchy
level.
[edit protocols]
l2circuit {
neighbor 192.0.2.5 {
interface ge-1/0/2.0 {
virtual-circuit-id 100;
encapsulation-type ethernet;
backup-neighbor 192.0.2.3 {
standby;
}
}
}
}
3. On Router PE4, configure the Layer 2 circuit by including the l2circuit statement at
the [edit protocols] hierarchy level. Include the neighbor statement and specify the
IPv4 address of the hub PE router. Configure the logical interface by including the
interface statement and specify the interface connected to Router CE4.
Configure the virtual circuit ID by including the virtual-circuit-id statement and
specifying 100 as the ID value at the [edit protocols l2circuit neighbor 192.0.2.5
interface ge-1/2/0.0] hierarchy level.
Configure the backup neighbor by including the backup-neighbor statement and
specifying the IPv4 address of the backup hub PE router. Router PE3 is the backup
neighbor in this example. Also include the standby statement at the [edit protocols
l2circuit neighbor 192.0.2.5 interface ge-1/2/0.0backup-neighbor192.0.2.3] hierarchy
level.
[edit protocols]
l2circuit {
neighbor 192.0.2.5 {
interface ge-1/2/0.0 {
virtual-circuit-id 100;
backup-neighbor 192.0.2.3 {
standby;
}
}
}
}
