[j-nsp] one-way lsp

OK, in the original config you pasted in, the local-address was missing.


Anyway, a wild guess, there could be a mismatch in the MTU size between
the interfaces. However, I'm not sure how the ERX counts the bytes so I
don't dare to give any suggestions. Anyone?

ibgp between the two routers is up (local address is configured). 

E-series interface config seems valid (e.g mpls and rsvp seem to be
enabled):

interface gigabitEthernet 4/0
 mtu 1522
 duplex full
 speed 1000
 link failover timeout 5000
 encapsulation vlan
! 
interface gigabitEthernet 4/0.100
 vlan id 100
 ip address 172.27.32.130 255.255.255.0
 ip ospf authentication-key <removed>
 mpls
 mpls rsvp profile default


In fact, according to the ERX, there is an RSVP session established
between itself and the J:

I'm mildly stumped.
