Weird ever since we enabled VRRP
we get this in our logs

jul/21/2005 11:08:13 incoming packet with unknown SPI
jul/21/2005 11:08:13 ipsec no sa found: proto=ah spi=3479836161 src=x.x.x.x
dst=y.y.y.y

Where x.x.x.x is our ip address on one of the interfaces and y.y.y.y is some unknown ip address !.

MT version 2.8.28

Please advise

These messages are not related in any way to VRRP. Somebody is trying to establish an IPsec tunnel with your router, and the router reports it is not configured to do so.
