Hello ITPro! Wondering if someone can comment on this experience regarding the routing of a host out of a VLAN using a pair of Nexus 3548 switches, SVIs with HSRP.
host contained within a VLAN and routed out by a pair of Nexus switches using SVI/HSRP.
NX1 SVI IP: 10.10.35.2/24 NX1 SVI IP: 10.10.35.3/24 HSRP VIP: 10.10.35.1
I was testing failover and monkeyed with the priority of the HSRP group, all seems to work no matter which Nexus switch is the active HSRP partner, works as expected.
If I shut down one of the SVIs to simulate a failure, all seems to work. Host inside VLAN is able to route out. I can even enable the SVI, then disable the SVI on the second Nexus switch and all is still well.
If I shut down both SVIs, traffic stops for the host inside the VLAN, totally expected. However, I can’t get things flowing again until both SVIs are enabled. If just enabling one, the host still fails to route.
Have any idea why that would be happening?
Here is a snip of the vPC config.
vcp domain 1 peer-switch role priority (1|2) <depending on what switch you are looking at in the pair peer-keepalive destination x.x.x.x peer-gateway layer3 peer-router auto-recovery
I tried to make this bite sized and not include the entirety of the config. Hopefully this description has the important parts, but if you need more info before you can comment, just let me know. Thanks again for your thoughts!
