I have an EIGRP domain.
r6 ---serial-------- r9
| |
ethernet ethernet
| |
r7 ---token ring ---r8
I can ping all around. The route table showes r7 to r9 through token
ring. If I shut the token ring I can ping r9 the other
way.
However the route table doesn't show two paths from r7 to r9. I don't
understand why not.
