Hello group,
I have a task where I'm asked to do a backup of a frame-relay circuit
using OSPF. The backup line is a dedicated serial line encapsulated with
ppp. The wording is as follow:
Configure area 0 on the ppp link between R4 and R5
The ppp link will be a backup of of frame-relay connection between R4
and R5 (both using major interfaces, R5 hub, R4 spoke). Configure the
network in such a way that this link is only used if R4 (a spoke) loses
its connection to the frame-relay cloud.
My obvious solution to this is just to increase the ospf cost of the
interfaces involved on the ppp link, in order that it does not show up
as the preferred path between R4 and R5.
My doubt is that perhaps this solution may be too obvious, and perhaps I
am missing something...
Any suggestions or alternative ways of doing this? Am I just being
paranoid about complexity?
Thank you
Gustavo Novais
