no neighbor <ip-addr> soo <soo-val>
Function:
Configure the site-of-origin from the neighbor route; the no operation will delete the configuration.
Parameters:
<ip-addr> the neighbor’s ip address, in dotted-decimal format.
<soo-val> is the site-of-origin, in the same form as RD.
Default:
Not configured.
Command Mode:
VRF Address Family Configuration Mode.
Usage Guide:
If the customer AS is connected with multiple ISP devices, configuring this attribute can prevent the
customer route from returning to the customer after passing the P area. This configuration will
propagate once set. The route with the SOO attribute won’t propagate to the neighbor already
configured with this attribute.
Example:
Switch(config)#router bgp 100
Switch(config-router)#address-family ipv4 vrf DC1
Switch(config-router-af)#neighbor 11.1.1.64 remote 200
Switch(config-router-af)#neighbor 11.1.1.64 soo 100:10
After configuring this attribute, the switch won’t propagate the remote route with the 100:10 rt
attribute to 11.1.1.64. (To be clear, the soo attribute will be checked together with other rt attributes,
that is to say, the neighbor will be treated as the original neighbor no matter it is or not, once the rt is
configured with the same attributes. In fact, soo is usually configured separately with a value
different with rt/rd, and is unique in the reachable area to describe the origin accurately).
77.17 rd
Command:
rd <ASN:nn_or_IP-address:nn>
Function:
Configure the RD (Route Distinguish) of VRF.
Parameters:
ASN:nn_or_IP-address:nn：The IP address format of the switch ID. ASN is AS ID, ranging from 1 to
4294967295, it can be shown in decimal notation (such as 6553700) or delimiter method (such as
100.100); IP-address is IP address that the length is 4 bytes; nn is arbitrary number that the length
is 2 bytes.
