vPC + SVI Knowledge

[Pramode Meghanath Liyanawadu Gamlathlage.]

HI All,

Just wanted to get and idea about how "vPC works with SVIs"

lets say i have following setup:

N9k-Sw1:(primary on VPC)

interce vla 300

ip address 10.10.10.1/25

N9k-Sw2:(scondary on VPC)

interface vla 300

ip address 10.10.10.2/25

the host(10.10.10.20)/25 from vlan 300 can have only one gateway(lets say 10.10.10.1/25 from N9k-sw1).

what happens when the N9k-sw1 is down ??? which means SVI:10.10.10.1 is down. ryt ?

how host will find its way to FW ?

note:plz find attached diagram

Hi

you will need to configure VRRP/HSRP/GLBP/etc.. on both N9k, also vlan 300 must be allowed on vPC peer link.

We have similar topology and about 100 subnets and VRFs - everything works fine.
