Strange problem. I have a L3 switch that has an IP link to another switch with a primary and an alternate IP address.
When I ping off of that switch, the first hop shows as follows:
1 10.52.252.58 0 msec primary add
10.52.252.57 0 msec alt address
10.52.252.58 4 msec primary add
2 10.52.252.18 0 msec 0 msec 0 msec
Any idea why it bounces between the two?
