Answered Question
Feb 7th, 2007

lab test config

wan_rtr (new)-10.10.150.1

wan_rtr )old)-172.16.0.1

problem:

wan_rtr(new) cant ping any vlans on 3750_new (it can ping 10.10.151.2)

wan_rtr(new) cant ping 3750_old, 2950(old)

wan_rtr(old) CAN ping 3750(old), 2959(old)

wan_rtr(old) can't ping any vlans on 3750_new

summary: can't ping between the two networks.

I'm sure this is simple routing issue but i'm missing it somewhere. thanks for any help.

I have this problem too.

You are missing some configuration:

2950 new:

ip default-gateway 10.10.151.1

3750 New:

ip routing

ip route 0.0.0.0 0.0.0.0 10.10.150.1

3750 Old:

ip default-gateway 172.16.0.11

2950 Old

ip default-gateway 172.16.0.11

WAN Router:

ip route 10.10.152.0 255.255.255.0 10.10.150.2

ip route 10.10.151.21 255.255.255.224 10.10.150.2

THe above should solve your connectivity issue,
