Configuring the Router MAC Address
On VSS, all routing protocols are centralized on the active supervisor engine. A common router MAC
address is used for Layer 3 interfaces on both active and standby switches. Additionally, to ensure
non-stop forwarding, the same router MAC address is used after switchover to Standby, so that all layer
3 peers see a consistent router MAC address.
There are three ways to configure a router MAC address on VSS:
• HHH—Manually set a router MAC address. Ensure that this MAC address is reserved for this usage.
•
chassis—Use the mac-address range reserved for Chassis. This is the Cisco MAC address assigned
to the chassis.
•
use-virtual—Use the mac-address range reserved for the VSS. This is the served Cisco MAC address
pool, which is derived from a base MAC avvs domain-id.
By default, the virtual domain based router MAC address is used. Any change of router MAC address
configuration requires a reboot of both VSS supervisor engines
The follow table shows how to configure the router MAC address.
