Hi guys,
I have to replace two old c6500 with two new C9300 switches in my DC.
My old C6500 is running ISIS config up against our Nexus 7k and that work like a charm.
My new C9300 also runs ISIS config up against our Nexus 7k and the ISIS is comming up all is good, but my connected switches, interface vlan is not been redistributed to our Nexus 7K.
From the the 7K I can ping the interface vlan on my C9300, but I cannot ping the next switch behind the C9300.
From the C9300 I can ping all switches there is connected to it.
I have compared config from the my C6500 to my C9300 and they are more or less look the same.
My ISIS config from C6500:
router isis 1
net 49.6600.0010.0255.0011.0239.00
is-type level-2-only
authentication mode md5 level-2
authentication key-chain SOLAR level-2
metric-style wide
set-overload-bit on-startup 30
no hello padding point-to-point
redistribute connected
passive-interface default
no passive-interface TenGigabitEthernet1/1/8
My ISIS Config from C9300:
router isis 1
net 49.6600.0010.0255.0011.0240.00

authentication mode md5 level-2

Alright I got the issue fixed today with TAC. :)
It was so simple that I did not even think that thought.... :) I was missing ip routing in the config.... Ups..

Hi Rick,
What should that Help? Just so i understand what the impact can be here. ☺

I just use that as a first step. Not saying it will do anything. In the past I have run into several issues with different platforms and routing auth.

Weird, has to be some weird bug with the new CatN9K.
11-10-2017 10:32 AM
Is the MTU setting the same on the CaT 9K
