Pinging multiple loopback interfaces
Edit: I went back and re-config everything from beginning and it worked, not sure why it didn't work in the previous configuration.
I setup a 7200 using multiple loopback interface (0, 48-51, 70) but I was only able to successfully ping the local loopback 0.
loopback 1 - 172.16.12.1
loopback 48 - 172.168.48.1
.
.
loopback 70 - 172.168.70.1
From 'sh ip int bri' & 'sh ip route', it shows both up and directly connected. I then did a 'debug ip packet' and ping the loopback ip and it shows as being unroutable.
The issue seems to come from the fact that loopback 1 and the rest of the loopbacks are in different subnets. Furthermore, I tested it by creating loopback 47 as 172.16.2.1. Surely enough it worked.
But why does it matter that the loopback interfaces are in different subnets when they are both local interface? I have also disabled cef and added in 'network 192.168.0.0
