Parameters
Example
This example shows how to enable the inbound soft reconfiguration for the neighbor
172.16.10.1. All the updates received form this neighbor will be stored unmodified,
regardless of the inbound policy.
DXS-3600-32S#configure terminal
DXS-3600-32S(config)#router bgp 65100
DXS-3600-32S(config-router)#neighbor 172.16.10.1 remote-as 65200
DXS-3600-32S(config-router)#neighbor 172.16.10.1 soft-reconfiguration inbound
DXS-3600-32S(config-router)#
IP-ADDRESS Specifies the IP address of the peer.
PEER-GROUP-NAME Specifies the name of the peer group.
SOO-VALUE The Site of Origin attribute will be encoded as a Route Origin Extended Community.
There are two different types for this attribute:
• IP address:number: The IP address should be a global IP address that is
assigned to the user and the number is assigned from a numbering space that is
administered by the user. The number can be 1-65535.
• AS number:number: The AS Number should be a public AS Number (Both 2-
bytes AS number and 4-bytes AS number works) that is assigned to the user and
the number is assigned from a numbering space that is administered by the user.
The number can be 1-4294967295 for 2-bytes AS number and 1-65535 for 4-
bytes AS number.
Default
No Site of Origin attribute configured by default.
Command Mode
Address Family Configuration (VRF).
Command Default Level
Level: 8. (EI Mode Only Command)
Usage Guideline
Use this command to set the SoO value for a BGP neighbor or a peer group.
The SoO extended community is BGP extended communities attribute that is used
to identify routes that have originated from a site so that the re-advertisement of that
prefix back to the source site can be prevented. The SoO extended community
uniquely identifies the site from which a router has learned a route. BGP can use the
SoO value associated with a route to prevent routing loops.
Use the show ip bgp neighbors or show ip bgp peer-group command to verify
your settings.
Example
This example shows how to set the Site-of-Origin value of BGP peer 3.3.3.3 in VRF
vpn1.
DXS-3600-32S#configure terminal
DXS-3600-32S(config)# router bgp 10
DXS-3600-32S(config-router)# address-family ipv4 vrf vpn1
DXS-3600-32S(config-router-af)# neighbor 3.3.3.3 remote-as 20
DXS-3600-32S(config-router-af)# neighbor 3.3.3.3 soo 10:100
DXS-3600-32S(config-router-af)# exit- address-family
