Single Cisco router with 2 VRF's. Route leak

[Maxim Bezzubov]

Hi.

have 2911 with ISP DSL link and fiber. 2 DMVPN tunnels with these source. For those was created 2 VRF.

Now have need to establish BGP session to neighbor which is located behind the fiber (GE 0/0 int). Need to export route from vrf to global.

interface ATM0/0/0
 ip vrf forwarding vrf1
 no ip address
 no atm ilmi-keepalive
 pvc 0/35
  encapsulation aal5snap
  pppoe-client dial-pool-number 1
 !
!
interface Dialer1
 ip vrf forwarding vrf1

 

interface GigabitEthernet0/0
description Fiber

ip vrf forwarding vrf2
 ip address 172.30.149.2 255.255.255.252
 duplex auto
 speed auto
 no cdp enable

router bgp 65149
 bgp router-id 172.30.149.2
 bgp log-neighbor-changes
 network 172.30.149.0 mask 255.255.255.252
 neighbor 172.30.149.1 remote-as 65149
 

ip route 172.30.149.0 255.255.255.252 GigabitEthernet0/0
ip route vrf vrf1 0.0.0.0 0.0.0.0 Dialer1
ip route vrf vrf2 0.0.0.0 0.0.0.0 172.30.149.1 - next hop is behind the GigabitEthernet0/0
 

I have tring this http://www.cisco.com/c/en/us/support/docs/multiprotocol-label-switching-mpls/multiprotocol-label-switching-vpns-mpls-vpns/47807-routeleaking.html#global

to add a static route

sh ip route vrf vrf2

Gateway of last resort is 172.30.149.1 to network 0.0.0.0

S*    0.0.0.0/0 [1/0] via 172.30.149.1
      172.30.0.0/16 is variably subnetted, 2 subnets, 2 masks
C        172.30.149.0/30 is directly connected, GigabitEthernet0/0
L        172.30.149.2/32 is directly connected, GigabitEthernet0/0

static route is added successfully

sh ip route

S        172.30.149.0/30 is directly connected, GigabitEthernet0/0
 

 but ping wasn't successful. Whats wrong?

[Richard Burts]

What were you pinging? Are you sure that whatever you were pinging has a route back to your address?

I have tring to ping IP 172.30.149.1 (that was behind the 172.30.149.0/30 GigabitEthernet0/0, connected directly to that interface) but has no success.

ping IP of interface is ok:

#ping 172.30.149.2
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 172.30.149.2, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/1/1 ms

ping 172.30.149.1
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 172.30.149.1, timeout is 2 seconds:
.....
Success rate is 0 percent (0/5)

have only 1 static route:

ip route 172.30.149.0 255.255.255.252 GigabitEthernet0/0

Can you post the output of show arp

traceroute might help too. I thought you achieve VRF route leak with route import and exports?

[Maxim Bezzubov]

I trying this http://www.cisco.com/c/en/us/support/docs/multiprotocol-label-switching-mpls/multiprotocol-label-switching-vpns-mpls-vpns/47807-routeleaking.html#global

import-export and MP-BGP I thought inter-VRF only. BHW I trying this - no success.

I need to route leak from VRF to global.

It is funnu but in this case traceroute is successfull but no ping and no bgp establish from this interface.

[Maxim Bezzubov]

it is an emply. trying to make a static arp - no success.

[Richard Burts]

If 172.30.149.1 is an address on a connected interface and if the arp table is empty then that suggests that there is a layer 2 issue with connectivity. If arp request and arp response are not working then there is no way that ping can work.

Hello

MBGP requrie the use of address family identifiers - can you try this?

no router bgp 65149

router bgp 65149
 no synchronization
 bgp log-neighbor-changes
 no auto-summary

 address-family ipv4 vrf vrf2
  neighbor 172.30.149.1 remote-as 65149
  neighbor 172.30.149.1 activate
  no synchronization
  network 172.30.149.0 mask 255.255.255.252
 exit-address-family

sh bgp all summary
sh bgp vpnv4 unicast all

Yeah! Great! No need to do a route leak. Bgp on vrf is working as well as in 'normal' mode, just a 'show' command looks a slight different.
