Re: Dual DMVPN cloud with 1 hub terminating two tunnels, equal

Hi Dale,

R2 (spoke that injected some eigrp routes)
R7 hub
R6 spoke that I see routing table of it that gets route from spoke R2.

I already changed bandwidth on R6 and R2 spokes. but nothing would have
changed.

I still have equal path in routing table.

Cheers,
