Hi folks,
It is interesting that there seem to be only two options to accomplish anycast
GWs for the L2 subnet with selection based on closest proximity to a GW (would
have thought there’re plenty of solutions out there with all the DC hype dating
several years back).
I only found Anycast HSRP with fabric path and the Distributed Anycast GW for
VXLAN with MP-BGP EVPN Control Plane –but that one seem to be only for the big
boys :)
Has anyone played with Anycast HSRP with fabric path please?
Just would like to confirm I understand it correctly.
So ISIS calculates best path to the anycast switch ID advertising the HSRP MAC
and since I can manipulate metrics on links between spine and leaf switches I
should be able to dictate which leaf switches should be using which GWs right?
Because only paths to anycast switch ID with equal costs are considered for
multipathing right? (i.e. there’s no unequal cost load sharing correct?)
Thank you
adam
