Announce BGP Prefixes to iBGP Peers

Use the neighbor announce-rpki state command to send the RPKI state to its iBGP neighbor within the extended community attribute. This command also causes this device to receive RPKI state with prefixes from the configured iBGP neighbor. This is only enabled when the send-community extended is enabled in the address family mode.

1. Navigate to the router bgp context.
   

   SLX(config)# router bgp
   SLX(config-bgp-router)#
                       

2. Navigate to the address-family context. Choose the correct address family that you want to configure this setting for.
   

   SLX(config-bgp-router)#
   SLX(config-bgp-router)# address-family ipv4 unicast
   SLX(config-bgp-router)# 
                       

3. Enable the send-community extended for this address family
   

   SLX(config-bgp-router)# neighbor 10.10.11.1 send-community extended
   SLX(config-bgp-router)# 
                       
4. Enable announcing RPKI state to the neighbor
   

   SLX(config-bgp-router)# neighbor 10.10.11.1 announce-rpki-state 
   SLX(config-bgp-router)#
                       

   RPKI prefixes and state information is now exchanged with the configured iBGP peer.

Example

The following example summarizes the commands in this procedure. This command enables sharing of prefixes and state information with the configured iBGP peer.

SLX# configure terminal
SLX(config)# router bgp 
SLX(config-bgp-router)# address-family ipv4 unicast 
SLX(config-bgp-ipv4u)# neighbor 10.10.11.1 send-community extended
SLX(config-bgp-ipv4u)# neighbor 10.10.11.1 announce-rpki-state 
SLX(config-bgp-ipv4u)#
