Just got through with a simple igrp-ripv1 redistribution exercise. No biggie
here. Just testing my memory of commands.
In any case, the useful tools -
Debug ip rip - to see if the routes you think are being redistribute really
are, and with the metric you think you have assigned
Debug ip igrp transactions - for the same reason. Did this on all the
routers in the chain, and watched how the metric changed across each link.
not that I want to spend time calculating (e)igrp metrics to see if my calcs
and the real results match. But the tool is there, at least
Points of minor interest / beware of:
There are no sh ip igrp commands available ( ios 11.3.something )
Hop counts / metrics: the lab called for igrp routes to be redistributed
into RIP with certain hop counts / metrics
The book answer did something slightly different than my answer, so now I am
wondering about best practice / reality in hop counting
Ethernet_1----routerA----link33------routerB-------link44-------routerC-----
-ethernet_2
>From ethernet 1 to Ethernet 2 hop count is 3?
If I am counting hops to an ethernet off of router B, the hop count is the
same as the hop count for the link44 off of routerB?
Just wondering about counting conventions. If an instruction states to
redistribute a route with a metric reflecting the accurate hop counts, is it
convention/best practice/reality to consider that any interface off a given
router is the same hop count distant?
I.e from ethernet 1, the hop count to B ethernet is the same as the link44
hop count is the same as the routerB link 33 address?
A minor point, as I said, and does not amount to being worth much discussion
