Hello,
I've being trying to setup a couple of branches with IWAN. APIC-EM is reachable from INET (static nat to the inside) and from the MPLS through BGP advertisement. The Branch with only INET link works flawlessly (NAT option used in APIC-EM), the problems start when the MPLS is in use.
Config:
*** Interface connecting to PE PPP
interface GigabitEthernet1
ip address 198.10.1.2 255.255.255.252
negotiation auto
*** BGP Peering with MPLS PE ***

Configuration GigabitEthernet1 after IWAN changes:
interface GigabitEthernet1
bandwidth 300000
ip vrf forwarding IWAN-TRANSPORT-1
ip address 198.10.1.2 255.255.255.252
negotiation auto
end
This makes the BGP peering to be removed and IWAN setup fail.
I've tried a couple of options without success:
- I've added the BGP into vrf after, but the PFR doesn't get used because the site still appears as failed in IWAN app and needs to be removed before it's added again.
- Tried to create the vrf and BGP in vrf before IWAN deployment. It's fails since IWAN validates for existing vrf's.
Anyone can shed some light for possible solutions ?
Thank you
