I had a N2048 switch connected to our network with an IP address on a vlan with a static default route.
I made the following changes to the switch and the switch was no longer available to telnet \ ssh \https.
* Added loopback address 10.250.8.105/32 to the loopback0 interface
* Added RIPv2 routing to transmit the loopback interface's address
* RIPv2 from network delivers the route 0.0.0.0/0 to the switch.
After the changes:
* Cannot use telnet \ ssh \ https to contact the switch from routed networks
* Can use networks that are directly connected to the switch to connect.
* AAA no longer works
* Switch is pingable via the loopback and the vlan interface
* SNMP (UDP) works fine with the switch
* Syslog based logging still work from the router
I have other N-Series (N3048 and N2048) that is showing the same issues and I have some that actually work fine (all the working are N3000). This the first N2000 that I have converted to RIP
It feels like the system is not using the routing table or that the TCP connection is not completing due to some stateful connection checking out differing interfaces.
Routing Table:
Default Gateway is 10.8.0.20
R *0.0.0.0/0 [120/2] via 10.8.0.20, Vl100
S 0.0.0.0/0 [250/0] via 10.8.0.10, Vl100
C *10.8.0.0/24 [0/1] directly connected, Vl100
C *10.250.8.105/32 [0/1] directly connected, Lo0
Switch Configuration:
* Version 6.1.1.7
