Hi Experts ,
We have SVis configured on Nexus 7718 switches , which are part of area 0 and fabripath is running between them. We are running OSPF as IGP and We have EGBP with Palo alto Firewall.
whenever we are redistributing ospf into bgp and vice-versa we are not getting ospf routes into BGP and bgp routes into OSPF.
we are using 4byet AS numbers ie 10.1 , 10.2 and 10.200 and also we are using community list.
nexus 7k config :
interface Vlan19
no shutdown
no ip redirects
ip address 10.10.10.2/24
no ipv6 redirects
ip ospf passive-interface
ip router ospf 20 area 0.0.0.0
hsrp 19

interface Vlan20

set extcommunity 4byteas-generic transitive 10.3:99

IBGP is fine between nexus 7ks & EBGP is formed with Palo alto FW .main problem is that OSPF routes are not getting redistributed into BGP and vice-versa.
Could you please check above config and confirm whether extcommunity works in this case as we are using dotted AS numbers.
