Leak default route from vpn 0 BGP to vpn 1

Hi, im facing the next issue:

 

We have two branch with 1 mpls + 1 internet link.

 

Primary branch is publushing default route via BGP to the MPLS link, secondary branch is doing the same but with as-prepend on the default route.

 

When primary branch loses the internet link, service vpn (vpn 1) is not learning a default route via vpn 0, even while vpn 0 still has a default route learned via bgp on the MPLS link, i have tried several ways to acomplish this without luck.

 

vpn 1 config is very simple:

 

Primary:

vpn 1
interface ge0/0
ip address 192.168.1.1/24
no shutdown
!
ip route 0.0.0.0/0 vpn 0

 

 

Secondary:

vpn 1
interface ge0/0
ip address 192.168.3.1/24
no shutdown

!
ip route 0.0.0.0/0 vpn 0


Once internet on primary goes down, the route table for vpn 1 drops default route:

 

PROTOCOL NEXTHOP NEXTHOP NEXTHOP
VPN PREFIX PROTOCOL SUB TYPE IF NAME ADDR VPN TLOC IP COLOR ENCAP STATUS
---------------------------------------------------------------------------------------------------------------------------------------------
1 192.168.1.0/24 connected - ge0/0 - - - - - F,S
1 192.168.3.0/24 omp - - - - 3.1.1.1 private1 ipsec F,S

 

 

Whats the correct way to still have internet connection via the mpls link?

 

 

Thanks in advance !

Hi Juan,

As far as my knowledge goes, route leaking from vpn 0 to vpn 1 is not supported so far. This feature support is in the roadmap but not in available version.

I haven't tested it though...
