I wanted to do some analysis of the EIGRP topology table last night, so I fired up a small lab. I was especially interested in how external routes appear there and compare to internal entries. Like all good scientific endeavors, the whole thing got derailed when I made a realization.
Manipulating administrative distance (AD) is another way to help with a mutual redistribution scenario.
You can use route tags in redistribution scenarios to filter and/or manipulate routes.
EIGRP allows you to tag external routes. That is, any route redistributed into EIGRP can be tagged with a numeric descriptor from 0 to 4294967295. Aaron ConawayI shake my head around sometimes and see what falls out. That’s what lands…
What’s this? More IGP redistribution? Yes. Yes, it is.
Since I didn’t do too well on the test, here are some more notes on IGP redistribution.
I guess we would eventually discuss routing IPv6. It was inevitable.
I continue to love shoving one IGP route down another IGP’s throat.
I love shoving EIGRP into OSPF and vice versa. It makes me feel powerful.
I’m still looking at route redistribution, and the external route types threw me for a loop a bit.
