Configuring EBGP Multihop

EBGP Multihop enables you to establish a neighbor connection between two external peers that are not directly connected. Multihop is available only for eBGP and is not available in for iBGP. When the firewall has an external neighbor that does not have a direct connection, you can use the ebgp−multihop command to establish a neighbor connection.

To configure EBGP Multihop, configure routers R1 and R2 as follows:

On R1:
router bgp 6501
: bgp router−id 1.1.1.1
: neighbor 2011:11:11:11::2 remote−as 6502
: neighbor 2011:11:11:11::2 ebgp−multihop
 
address−family ipv6
: neighbor 2011:11:11:11::2 activate
exit−address−family
 
On R2:
router bgp 6502
: bgp router−id 2.2.2.2
: neighbor 2011:11:11:11::1 remote−as 6501
: neighbor 2011:11:11:11::1 ebgp−multihop
 
address−family ipv6
: network 1010::1/128
: network 2020::1/128
: neighbor 2011:11:11:11::1 activate
