Command or Action
Step 9
exit
Example:
RP/0/RSP0/CPU0:router(config-bgp-vrf-af)# exit
Step 10 neighbor ip-address
Example:
RP/0/RSP0/CPU0:router(config-bgp-vrf)#
neighbor 10.0.0.0
Step 11 remote-as as-number
Example:
RP/0/RSP0/CPU0:router(config-bgp-vrf-nbr)#
remote-as 2
Step 12 password { clear | encrypted } password
Example:
RP/0/RSP0/CPU0:router(config-bgp-vrf-nbr)#
password encrypted 234xyz
Step 13 ebgp-multihop [ ttl-value ]
Example:
RP/0/RSP0/CPU0:router(config-bgp-vrf-nbr)#
ebgp-multihop 55
Step 14
Do one of the following:
• address-family { ipv4 | ipv6 } unicast
• address-family {ipv4 {unicast |
labeled-unicast} | ipv6 unicast}
Example:
RP/0/RSP0/CPU0:router(config-vrf)#
address-family ipv4 unicast
Step 15 site-of-origin [ as-number : nn | ip-address : nn ]
Example:
RP/0/RSP0/CPU0:router(config-bgp-vrf-nbr-af)#
site-of-origin 234:111
Purpose
Exits the current configuration mode.
Configures a CE neighbor. The ip-address argument must be a
private address.
Configures the remote AS for the CE neighbor.
Enable Message Digest 5 (MD5) authentication on a TCP
connection between two BGP neighbors.
Configures the CE neighbor to accept and attempt BGP
connections to external peers residing on networks that are not
directly connected.
Specifies either an IPv4 or IPv6 address family unicast and enters
address family configuration submode.

command, use the CLI help (?).
Configures the site-of-origin (SoO) extended community. Routes
that are learned from this CE neighbor are tagged with the SoO
extended community before being advertised to the rest of the
PEs. SoO is frequently used to detect loops when as-override is
configured on the PE router. If the prefix is looped back to the
same site, the PE detects this and does not send the update to the
CE.
