Hello everyone.
I`m having strange issue with ldp-tunneling over rsvp lsp.
My network diagram looks like this:
RSVP sessions is istablished between two mx routers. ldp-tunneling is enabled:
label-switched-path LSP-1 {
from 172.18.2.1;
to 172.18.2.2;
ldp-tunneling;
}
traffic engineering is turned on MX104-1 and MX104-2
There is no traffic engineering in area 1.
on MX104-1 and MX104-2 interface lo0.0 is configured under protocols ldp.
on EX4600 ldp is turned on interfaces facing MXs and on interface between EX4600s and lo0.0.
So far so good. I got all loopbacks in ldp database and inet.3 tables.
So i configure l2circuit between two EX switches:
neighbor 172.18.1.254 {
interface xe-0/0/0.700 {
virtual-circuit-id 1000;
no-control-word;
encapsulation-type ethernet-vlan;
ignore-mtu-mismatch;
}
}
Circuit is up and running.
But when i tear link between two EX switches l2circuit goes down.
Neighbor: 172.18.1.254
Interface Type St Time last up # Up trans
xe-0/0/0.700(vc 1000) rmt OL
So after checking inet.3 table on EX4600-2 i see that all loopbacks there
172.18.1.254/32 *[LDP/9] 00:01:45, metric 1
> to 172.18.1.2 via xe-0/0/0.2, Push 312560
172.18.2.2/32 *[LDP/9] 00:00:45, metric 1
> to 172.18.1.2 via xe-0/0/0.2
172.18.2.1/32 *[LDP/9] 00:01:45, metric 1
> to 172.18.1.2 via xe-0/0/0.2, Push 312192
But from the side of EX4600-1 i can see only MX104-1 172.18.2.1/32.
While in ldp database i can see all FECs:
