Re: OSPF-IGRP Redistribution with IGRP having longer mask

create secondary addresses on igrp with the /29 mask and tunnel it to
ospf's /29...

btw, i use statics and sometimes defaults for my tunnels (following cisco's
examples on tunnels)...does anyone know if this is acceptable on the lab?
since technically it does violate the no static rule...is there anyone that
has an example of a tunnel without using them?
