Simple OSPF between two EX4300s

10.11.17   |  
a week ago

I am trying to get into OSPF and want to configure it between two switches, but I'm having some difficulty.

R1 & R2 with xe interfaces 10.5.0.1/24 and 10.5.0.2/24

Protocols{

 Ospf {

  area 0.0.0.0 {

   interface xe-0/2/3.0;

  }

 }

}

Both have a loopback address set:

R1: 192.168.0.1/32

R2: 192.168.1.1/32

Path: 192.168.1.1 <-> 10.5.0.1 <-> 10.5.0.2 <-> 192.168.0.1 

A "show ospf route" for R1 has R2s loopback address listed and R2 has R1s loopback, but cant ping with "No route to host" and I do not see the routes in the routing table.

The 10.1 and 10.4 addresses are IRB interfaces I will be using later.

You're missing lo0 in your ospf config.

That's it, I see my mistake now. I appreciate it, thanks.
