Display OSPF neighbor sorted by OSPF process ID

I had two issues with the show ip ospf neighbors command:

• It is not sorted by the OSPF process ID, so you get a mess if you have more than one OSPF process and don't specify the process ID in the show command
• It does not display the OSPF area the neighbor belongs to

To fix both problems, I wrote a Tcl script that displays OSPF neighbors sorted by process ID and includes the fields I wanted to have. To install it on your router:

1. Download it from my web site.
2. Copy the ospfNeighbors.tcl file to your router's flash (or NVRAM).
3. Define an alias, for example alias exec ospf tclsh flash:ospfNeighbors.tcl.

Here is a sample printout produced on my lab router:
