Chapter 4 Configuring Ethernet SPAs on Cisco IOS XR Software
Verifying the Interface Configuration
HSRP runs on top of User Datagram Protocol (UDP), and uses port number 1985. Routers use their
actual IP address as the source address for protocol packets, not the virtual IP address, so that the HSRP
routers can identify each other.
For more information on HSRP, refer to the “Implementing HSRP on Cisco IOS XR Software” module
of the Cisco IOS XR IP Addresses and Services Configuration Guide.
Verifying the Interface Configuration
Use the following task to display your router configuration settings.
