Re: IOS XR - ipv4 virtual address

Hello Atif,

in order to have a working virtual address both management interfaces need to have an IP address in the same IP subnet

see from one of our CRS:

sh ip int br | inc Mgmt
MgmtEth0/RP1/CPU0/0            10.85.17.50     Up                    Up     
MgmtEth0/RP0/CPU0/0            10.85.17.49     Up                    Up    

then you configure the virtual IP address in the same IP subnet

sh run | inc 10.85.17.
Building configuration...
ipv4 virtual address 10.85.17.51 255.255.255.240
10 permit ipv4 10.85.17.48 0.0.0.15 any
ipv4 address 10.85.17.49 255.255.255.240
ipv4 address 10.85.17.50 255.255.255.240

Hope to help

Giuseppe
