I was testing OSPF external routes recently and wanted to have a comprehensive display of OSPF type-5 LSAs (not the too-verbose information IOS generates), so I created a Tcl script that displays type-5 (external) LSAs from the OSPF database in a tabular format. You can download it from my web site (installation instructions are included in the Tcl source). Here is a sample printout from one of my lab routers:
External OSPF routes for OSPF process ID 1

> 10.1.0.2/32 5 E2 2 10.0.0.3
