- 3845 and l2tpv3 pseudowire problem
- Posted by Dmitry Melekhov on May 12th, 2008
Hello!
I have following configuration on cisco 3660 on one side :
l2tp-class sberbank
pseudowire-class eth-sberbank
encapsulation l2tpv3
protocol l2tpv3 sberbank
ip local interface Loopback0
interface Loopback0
ip address 192.168.200.249 255.255.255.252
interface FastEthernet0/0.4
description sberbank
encapsulation dot1Q 4
no cdp enable
xconnect 192.168.200.250 1 pw-class eth-sberbank
and mirror configuration on another side on 2801.
Now I want to migrate from 3660 to 3845.
l2tpv3 connection starts
p100-cr3845-2#sh l2tun
%No active L2F tunnels

but traffic don't pass.
I can see only arp requests pass this tunnel with tcpdump on both
sides.
What can be wrong?

1. The configurations wrt to the tunnel on the 3660 and 3845 are
identical ?
2. what is the IOS version in use on 3660 ?
3. what is the IOS version in use on 3845 ?

Is CEF enabled on the 3845 ?

Very strange thing is that arp requests pass (this mean that l2
connection exists), but other traffic not.
May be something is wrong with switches?
I don't phisically replaced 3660 with 3845, they both are connected
now.
But I tried to change connection from 2801 to 2811 on other side (they
are both connected too) and there are no problems...

I tested, switches works OK, mac address from far point moves to 3845
when I turn loopback 0 no shutdown and shutdown on 3660...

Are ARP replies being received ie. is the tunnel passing both
broadcast request and unicast response ?
Post
sh xconnect all detail
sh l2tun summary al

Just because I see mac addresses in arp tables on both sides I'm shure
that response pass.
There are no above commands . at least in 2.4.19...
