Hi, The following config is taken from a working Cisco to ERX link. This should be opened as a TAC case for further investigation, probably both with Cisco and Unisphere. ! interface POS3/0 description To ERX ip address 30.0.2.1 255.255.255.0 no ip directed-broadcast encapsulation ppp mpls label protocol ldp tag-switching ip crc 32 clock source internal ! interface GigabitEthernet4/0 ip address 30.0.1.2 255.255.255.0 no ip directed-broadcast no keepalive negotiation auto mpls label protocol ldp tag-switching ip ! router ospf 1 log-adjacency-changes network 30.0.1.0 0.0.0.255 area 0 network 30.0.2.0 0.0.0.255 area 0 network 100.0.1.1 0.0.0.0 area 0 ! ip classless ! end ERX(P) (erx_3-3-2p3-0.rel) RX-00-12-d0#sho config virtual-router default Please wait... !
