1. Unlike IOS, IOS-XR has the HSRP configuration done under a router process. Configure HSRP group 1 using the East-West link to R2.
   1. Answer option 1

      RP/0/0/CPU0:R1(config)#router hsrp
      RP/0/0/CPU0:R1(config-hsrp)#interface g 0/0/0/0
      RP/0/0/CPU0:R1(config-hsrp-if)#address-family ipv4
      RP/0/0/CPU0:R1(config-hsrp-ipv4)#hsrp 1
      RP/0/0/CPU0:R1(config-hsrp-gp)#address 10.0.0.1
      RP/0/0/CPU0:R1(config-hsrp-gp)#commit 

   2. Answer option 2

      RP/0/0/CPU0:R1(config)#router hsrp interface gigabitEthernet 0/0/0/0 address-family ipv4 hsrp 1 address 10.0.0.1
      RP/0/0/CPU0:R1(config)#commit
      Mon Dec 16 16:54:58.802 UTC

2. Repeat for R2 and set HSRP priority to 50
3. Commit for both routers
4. Verification
