14.11 PE-CE Routing with BGP

 

I found the error I have to peer to the right AS from customer to AS 1. Please close this topic

 

Hello

Is it possible to peer between R6 and SW1 or between R5 and SW2 between the Loopback addresses, I get always peer in wrong AS.

I had to activate EBGP-MULTIHOP. And I guess as-override is not working.

I have Lo0 and vlan 67 on vrf VPN_A

R6

router bgp 1
 no bgp default ipv4-unicast
 bgp log-neighbor-changes
 neighbor 150.1.4.4 remote-as 1
 neighbor 150.1.4.4 ebgp-multihop 255
 neighbor 150.1.4.4 update-source Loopback0 
 address-family ipv4 vrf VPN_A
  neighbor 150.1.7.7 remote-as 78
  neighbor 150.1.7.7 update-source Loopback0
  neighbor 150.1.7.7 activate
  neighbor 150.1.7.7 as-override
  no synchronization

 

SW1

router bgp 78
 no synchronization
 bgp log-neighbor-changes
 network 150.1.7.0 mask 255.255.255.0
 neighbor 150.1.6.6 remote-as 78
 neighbor 150.1.6.6 update-source Loopback0
 no auto-summary

I have no clue if this can be done without peering on the physical interfaces
