Supported on all 7210 SAS platforms as described in this document
This command configures the autonomous system number (ASN) for the router. A router can only belong to one AS. An ASN is a globally unique number with an AS. This number is used to exchange exterior routing information with neighboring ASs and as an identifier of the AS.
If the ASN is changed on a router with an active BGP instance, the new AS number is not used until the BGP instance is restarted either by administratively disabling and enabling (shutdown or no shutdown) the BGP instance or rebooting the system with the new configuration.
Specifies the AS number, expressed as a decimal integer.

Supported on all 7210 SAS platforms as described in this document
This command configures the router ID for the router instance.
The router ID is used by both OSPF and BGP routing protocols in this instance of the routing table manager.
When configuring a new router ID, protocols are not automatically restarted with the new router ID. The next time a protocol is initialized, the new router ID is used. This can result in an interim period of time when different protocols use different router IDs.
To force the new router ID to be used, issue the shutdown and no shutdown commands for each protocol that uses the router ID, or restart the entire router.
By default, the system uses the system interface address (which is also the loopback address). If a system interface address is not configured, use the last 32 bits of the chassis MAC address.
The no form of this command to reverts to the default value.
Specifies the 32-bit router ID, expressed in dotted decimal notation or as a decimal value.
