[j-nsp] LDP issue between M10i and ERX

[Junaid]

Hi,

I am trying to enable MPLS between ERX1440 and M10i routers. The
routers are connected via an Ethernet switch. I have three Cisco
routers on the same subnet as well. Strangely, all routers are able to
form LDP sessions with each other but M10i and ERX are not
establishing LDP session. Although both junipers are able to establish
LDP with three ciscos but they are not able to form LDP with each
other. I received the following debug logs on junipers:

Legend:
-----------
AAA.BBB.CCC.DDD : Loopback IP address of ERX
WWW.XXX.YYY.ZZZ : Loopback IP address of M10i


On M10i:

I have used the following config templates for junipers:


For Juniper (JunOS):

# set interfaces ge-0/1/0 unit 2 family mpls
# set protocols mpls interface ge-0/1/0.2

# set routing-options router-id <loopback 0 IP address>
# set protocols ldp interface ge-0/1/0.2
# set protocols ldp transport-address router-id


For Juniper (JunOSe):

#(config)# mpls
#(config)# mpls ldp

#(config)# interface g1/0
#(config-if)# mpls
#(config-if)# mpls ldp



Any idea what the issue could be?
