IOS-XRv and HSRP: Supported?

Question

Hey gang -
I'm building a virtual lab within a KVM hypervisor, and it includes 2 XRv images tied together across a VM switch image (Arista vEOS, but that's unimportant).  The L2 connectivity is clearly there between the two routers:
RP/0/0/CPU0:r2#show cdp neighbors gigabitEthernet 0/0/0/6
Fri Apr 17 10:49:07.505 UTC
Capability Codes: R - Router, T - Trans Bridge, B - Source Route Bridge
                  S - Switch, H - Host, I - IGMP, r - Repeater
Device ID       Local Intrfce    Holdtme Capability Platform  Port ID
r1                    Gi0/0/0/6        149     R          IOS XRv S Gi0/0/0/6
And HSRP is able to sync up appropriately between the two of them:
RP/0/0/CPU0:r2#show hsrp br
Fri Apr 17 10:46:32.806 UTC
IPv4 Groups:
                        P indicates configured to preempt.
                        |
Interface      Grp  Pri P State   Active addr     Standby addr   Group addr
Gi0/0/0/6         1 100 P Standby 172.17.0.242    local          172.17.0.241
IPv6 Groups:
However, r2 (the secondary) can't ping the HSRP IP at all.  It can ping the buddy router's IP address, but not the HSRP one:
RP/0/0/CPU0:r2#ping 172.17.0.242
Fri Apr 17 10:51:30.635 UTC
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 172.17.0.242, timeout is 2 seconds:
Success rate is 100 percent (5/5), round-trip min/avg/max = 9/17/19 ms
RP/0/0/CPU0:r2#ping 172.17.0.241
Fri Apr 17 10:51:32.595 UTC
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 172.17.0.241, timeout is 2 seconds:
Success rate is 0 percent (0/5)
The primary router can ping the HSRP IP though:
RP/0/0/CPU0:r1#ping 172.17.0.241
Fri Apr 17 11:32:32.679 UTC
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 172.17.0.241, timeout is 2 seconds:
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/1/1 ms
Further, the switch VM that the two XRv routers are connected to can ping both of their IPs on Gig0/0/0/6, but can't ping the HSRP IP:

(Pay no mind to the horrendous latency; it's due to the way Arista wrote the VM).
So after all of that: should I expect HSRP to be fully supported with XRv?  Or, like the L2 interfaces that are fully configurable, is it something that isn't supported?  Did I, perhaps, forget to enable some bit within the XRv's config?
Thanks!

Answer 1

In order to get redundancy to run between two SLB switches, you need to configure HSRP between the two VLAN interfaces and then associate the standby name with the Cisco IOS SLB Virtual Server (Vserver). When using IOS SLB in an HSRP environment ensure that the active HSRP router (also active for IOS SLB) is receiving the return traffic for the IOS SLB connections.
