Dears, I have an ASR1001 functioning as a LNS. User will use a 3G Modem to establish PPPoE to Provider's LAC and then terminate at the LNS via L2TP tunnel. I have assigned certain users to their proper VRF through AAA server so that it can be applied their peer ip, vrf and loopback interface on the virtual-access interface. 3G Modem can establish the connection to LNS and assign the VAI to specific VRF according to the return av-pair attribute. LNS also has another sub-interface to the PE router and assigned to the same VRF with the VAI for each user. However, I found that I can't ping from the 3G Modem to PE, on the contrary, PE can ping to the 3G Modem. The traceroute result from 3G Modem is stuck at the LNS and I can ping from the 3G Modem to LNS. I have checked that the vrf routing table on LNS has the route to PE. It's so strange that the 3G Modem can reach the LNS but not PE. Any idea?? _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
