Tim,

Also Bob is right,

Just In ISIS use....

distance x ip to all the routes, or distance x a.b.c.d w.x.y.z #acl to
define the source of the update and the routes!!!

Rgds,

Sergio

Hi Tim,

I think for OSPF and EIGRP you don?t have problems!!!

In ISIS I think you can use distance xxx ip 0.0.0.0 255.255.255.255 #acl

So, It permits all the routers!!! And the ACL defines the routes!!!

Rgds,

Asunto: Changing the preference of routes learned via different IGP's

Hi Guys,

I came across an interesting problem in a practice lab:

"In the future, additional routers may be added that will be running
different
routing protocols. Make Rx prefer routes learned via ISIS more preferable
than routes learned via OSPF and make routes learned via OSPF preferred over
routes learned from Eigrp."

My first thought was to use the distance command to meet this requirement,
but
this command requires the source address of the router from which routes are
learned. Since this will happen in the future, I don't know at this point
what source address to use.

Anybody have any ideas how this requirement can be met?

Thanks, Tim
