no-prepend disables local-as prepending on incoming EBGP updates;
replace-as replaces router's own AS with local-as on outgoing EBGP updates.

When I advertise 1.3.9.0/24 to my ISP they are seeing the as-path as..  345
64512

 

How do I get rid of 64512 so it's not sent as part of the as-path ?

 

My intentions were to use 64512 as my internal As that I use to run bgp between all my pe's for my internal mpls l3vpn's...

 

router bgp 64512

bgp router-id 10.10.0.10

address-family vpnv4 unicast

!

neighbor 10.101.12.253

  remote-as 64512

  update-source Loopback0

  address-family vpnv4 unicast

  !

!

vrf one

  rd 10.10.0.10:1

  address-family ipv4 unicast

   maximum-paths ibgp 2 unequal-cost

   network 1.3.9.0/24

 

  neighbor 1.2.3.4

   remote-as 789

   local-as 345

   address-family ipv4 unicast

    route-policy ipv4-allow-in in

    route-policy ipv4-allow-out out

 

I also tried the two ways  of removing private AS and this didn't work.

 

  neighbor 1.2.3.4

   remote-as 789

   local-as 345

address-family ipv4 unicast

  route-policy ipv4-allow-in in

  route-policy ipv4-allow-out out

  remove-private-AS entire-aspath

 

didn't work

 

  neighbor 1.2.3.4

   remote-as 789

   local-as 345

address-family ipv4 unicast

  route-policy ipv4-allow-in in

  route-policy ipv4-allow-out out

  remove-private-AS

 

didn't work
