Routes not showing in Routing Table - ASA 5512

GRANT3779 — Tue, 12 Mar 2019 07:25:33 GMT

I have just upgraded ASA image to 9.5.1 and notice that nothing shows in the routing table even though I have statics. Other ASAs I have on previous versions seem to be showing my statics. Routing from the ASA seems to be OK though. If I add a new static pointing it out the LAN interface it appears in the routing table. Just doesn't seem to show the ones pointing out the MGMT on 9.5.1

sh run route

route MGMT 10.44.128.0 255.255.240.0 172.28.37.1 1
route MGMT 10.44.142.0 255.255.255.0 172.28.37.1 1
route MGMT 10.44.144.0 255.255.240.0 172.28.37.1 1

sh route

Codes: L - local, C - connected, S - static, R - RIP, M - mobile, B - BGP
D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area
N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
E1 - OSPF external type 1, E2 - OSPF external type 2
i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2
ia - IS-IS inter area, * - candidate default, U - per-user static route
o - ODR, P - periodic downloaded static route, + - replicated route
Gateway of last resort is not set

sh route static

sh route MGMT

This ASA is in transparent mode, but so are my others which sh a routing table. I believe in transparent mode it will perform route lookup when traffic originates from ASA, e.g syslog.

Hi Aditya,

That works. The routing table is visible. Does anyone know why this has changed in the different code?

Thanks
