Hi,
Weird issue with an 887 connecting via Dialer to 3G(We run LNS the router is terminating on(7200)) - From 7200, can ping WAN IP assigned to 3G dialer:
ping vrf HOCA 172.18.35.2
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 172.18.35.2, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 80/83/96 ms
From CE can ping 7200 loop:
#ping 172.18.35.1
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 172.18.35.1, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 80/318/1212 ms
CE has default route of dialer:
#sh ip route 0.0.0.0
Routing entry for 0.0.0.0/0, supernet
Known via "static", distance 1, metric 0 (connected), candidate default path
Routing Descriptor Blocks:
* directly connected, via Dialer2
Route metric is 0, traffic share count is 1
7200 has route for CEs LAN (192.168.130.0/24):
>sh ip route vrf HOCA 192.168.130.0
Routing entry for 192.168.130.0/24
Known via "static", distance 1, metric 0
Redistributing via bgp 17766
Advertised by bgp 17766
Routing Descriptor Blocks:
* 172.18.35.2
Route metric is 0, traffic share count is 1
But cannot ping lan IP of CE:
>ping vrf HOCA 192.168.130.1
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 192.168.130.1, timeout is 2 seconds:

Success rate is 0 percent (0/5)
vlan is definitely up on CE:
#sh int vlan 1
Vlan1 is up, line protocol is up

If I debug icmp, I am seeing unusual output(In that I have never seen "topology BASE, dscp 0 topoid 0" etc)
icmp that is working seems to be marked as dscp 10, where the icmp that isn't working is marked as dscp 0(probably coincidence)

IOS is c880data-universalk9-mz.151-1.T1.bin
CE config is one we use for all vrf CE's (no nat, no acl's - very simple config), and the 7200(LNS) has 00's of DSL tails terminating on it that work without issue.
Any suggestions are greatly appreciated.
