Redis Nexus

[debascx]

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...
