I cannot ping from my Cisco 9300 switch to another subnet on our network but I can ping from a PC on that switch to another subnet on our network. Why can I not ping from within the switch? I have a couple of switches on other subnets that can ping out, but I don't see anything in the configuration being different that would affect icmp.
The solution was to add our inside IP block to BGP to allow it to traverse the network. Not sure how it was working before but we did upgrade to IOS 17.3.5 on our Catalyst 9300s, must've been some kind of bug that broke it in the upgrade.
The switch is connected to an ASA on the inside interface that is doing our routing. On the switch we have ip route 0.0.0.0 0.0.0.0 "ip of the inside interface" of the ASA.
