Hi,
I could need your help!! And that's about it I want to convert a Nexus 9372PX to Layer 3. The connection between Core and Nexus is eBGP the local routing should run with OSPF. Have it on a Cat 9500 running because there are no problems on the Nexus I can not run it.
here's the excerpt from the Cat 9500:
router ospf 1
router-id 10.211.2.1
area 0.0.0.0 authentication message-digest
redistribute connected subnets
passive-interface default
network 10.103.0.0 0.0.255.255 area 0.0.0.0
network 10.211.0.0 0.0.255.255 area 0.0.0.0
!
router bgp 64534
bgp router-id 10.211.2.1
bgp log-neighbor-changes
bgp deterministic med
redistribute ospf 1
neighbor 10.103.10.29 remote as 64527
neighbor 10.103.10.29 description ### eBGP to SC10100 ###
neighbor 10.103.10.29 password 7 XXXXXXXXXXXXXXXXXXX
neighbor 10.103.10.29 update-source port-channel128
neighbor 10.103.10.29 next-hop-self
neighbor 10.103.10.29 send-community both
neighbor 10.103.11.29 remote as 64527
neighbor 10.103.11.29 description ### eBGP to SC10200 ###
neighbor 10.103.11.29 password 7 XXXXXXXXXXXXXXXXXXX
neighbor 10.103.11.29 update-source Port-channel127
neighbor 10.103.11.29 next-hop-self
neighbor 10.103.11.29 send-community both
With this conf I can reach all networks which are displayed via sh ip bgp !!
There is the abstract from the nexus:
ip prefix-list ALL-NETWORKS seq 5 permit 0.0.0.0/0 le 32
route-map ALL-NETWORKS permit 10
match ip address prefix-list ALL-NETWORKS
router ospf 1
router-id 10.208.2.5
network 10.103.0.0/16 area 0.0.0.0
redistribute bgp 64628 route-map ALL-NETWORKS
log-adjacency-changes
area 0.0.0.0 authentication message-digest
timers throttle spf 10 100 5000
timers lsa-arrival 80
timers throttle lsa 10 100 5000
auto-cost reference-bandwidth 10000
passive-interface default
router bgp 64628
address-family ipv4 unicast
network 10.208.2.5/32
redistribute ospf 1 route-map ALL-NETWORKS
neighbor 10.103.10.41
remote as 64527
description ### eBigg uplink to SC10100 ###
password 7 XXXXXXXXXXXXXXXXXXXXXXXX
update-source port-channel4096
address-family ipv4 unicast
send-community both
next-hop-self
Only from the Nexus I can not IP pinging is displayed under sh ip BGP!
And my knowledge in the field Nexus not so big !!
Thanks & Greetings
Bastian

Hello,
what are the Nexus and the Catalyst connected to, what are the BGP neighbors ? Post the full configs and a schematic drawing of your topology, as it is unclear what is connected to what...
