Hello All,
Refer: attached network architecture design
I have a network design as attached. Currently we are migrating from IPv4 to IPv6 in our organization & are stuck with one issue. Below is the config from Cisco 6509 catalyst switch for your reference.
CONFIGURATION of Cisco 6509 Catalyst Switch:
Interface Configs:
!
Interface Te3/2
vrf forwarding PUB
ip address 10.240.2.5 255.255.255.0
no ip redirects
no ip unreachables
ipv6 address 2403:BE80:1000::1/39
ipv6 enable
End
!
Vlan 25
!
interface Vlan25
vrf forwarding SHARED
ip address 10.190.4.254 255.255.255.128
no ip redirects
no ip unreachables
ipv6 address 2403:BE80:2000::1/39
ipv6 enable
End
!
Interface Fa4/32
Switchport
Switchport access vlan 25
Switchport mode access

PROBLEM DESCRIPTION:
- When i try to ping the interface Te3/2 IPv6 address (under vrf PUB) from the PC connected under SHARED vrf, i am not able to ping it. i have done route leaking between vrf PUB & vrf SHARED as can be seen from the config above.
- Cisco 6509 switch itself is not able to ping the IPv6 address configured on Te3/2 if pinged from SHARED vrf & vice versa.
Both the Networks (1000 & 2000) are seen in the ipv6 routing table under their specific vrf's as ebgp learned routes, but not able to ping each other. Output is as under
Cisco6509#sh ipv6 route vrf SHARED

Can anybody put some light on this above issue? do let me know if anything else needs to be configured to achieve inter vrf routing under IPv6.
Please note that with IPv4 it is working perfectly fine with same config as above.
Awaiting for a solution.
With best Regards,
Sunny
