Well,
IS-IS or OSPF?
Q: And don't you need at least RSVP for the LDP signaling? But
since he didn't change nothing beside the L2 switches... Not relevant
(maybe).
I had a hard time passing IS-IS thru Extreme Switch, give up after
5m and used OSPF for that segment of our Pre-Prod Lab.
( Since its only for a redundant MX it don't matter much to
perfectly match Prod for that part )

No. Both of the MX routers are using the same interfaces.
The only thing that has changed was the switches (l2 path) between them.
*Do your control plane filters still permit ldp on both ends*?
Yes

Hello people,
There's a weird problem I would like to share with you.
I have the following scenario:
MX104 -> L2 SW (1) -> L2 SW (2) -> MX80
Both L2 SW are Extreme X460 and they're doing nothing except forwarding
frames at layer 2.
In order to simplify our topology, we have changed the MX104 uplink to L2
SW (2) so the topology went to MX104 -> L2 SW (2) -> MX80.
After that, the BGP sessions went up and all the traffic has returned as
expected, however I have three l2circuit connections (vlan-ccc mode) and
they went to "Down (OL)" status at one side and Up at another. In order to
reestablish them we had to do a rollback of the physical changes we did.
As it just don't make any sense to me, I summon you experts to help me with
that, so we can try to figure out what went wrong.
Additional details: I'm using LDP signaling at both sides. It' a point to
point L3 connection, so I have the loopback interfaces configured at both
sides and a /30 between them, also I have static routes to reach their
loopback interface's addresses.
Any help will be appreciated.
Cheers,
Caio
