Hey guys,
I'm trying to wrap my head around the eigrp stub command. Here is my
topology (taken from IE wb lab 11 task 4.8 if you have that, if not I'll
explain below, pretty easy to follow).
fully meshed frame connection between R2, R3, and R5. R5 has an ethernet
connection to R6. All those interface are in eigrp 10. I don't want Query
messages to be sent to R2 in the case of a route in the EIGRP domain being
lost;
Rack1R2#srb router eigrp 10
router eigrp 10
redistribute connected metric 10000 1000 100 1 1500 route-map C->EIGRP
network 187.1.235.2 0.0.0.0
no auto-summary
eigrp router-id 150.1.2.2
*eigrp stub connected summary*
Okay, on R6 I shutdown the ethernet interface, causing that route to be lost
in the eigrp domain. Before doing that I logged debug ip eigrp packet to
R2's buffer and get the following output.
My question is, am I going about verifying this the correct way? If not can
somebody shed some light in that regards. I'm sure there is something
fundamental that I am missing.
Thanks!!!
