HP 2920 Mgmt IP Problem

Hello

i have a very stange issue, no idea what this can cause. In this network topology, a few HP2920 are connected to a coreswitch. 

Switch1 has following config:

 

ip default-gateway 10.254.254.1

vlan 1
   name "MGMT"
   ip address 10.254.254.2 255.255.255.0

oobm
   ip address 10.254.254.2 255.255.255.0
   ip default-gateway 10.254.254.1

 

Gateway is reachable

 

config)# ping 10.254.254.1
10.254.254.1 is alive, time = 5 ms

 

 

Switch2 has following config:

 

ip default-gateway 10.254.254.1

vlan 1
   name "MGMT"
   ip address 10.254.254.3 255.255.255.0

oobm
   ip address 10.254.254.3 255.255.255.0
   ip default-gateway 10.254.254.1

Gateway is reachable

 

ping 10.254.254.1
10.254.254.1 is alive, time = 5 ms

 

Both switches can ping each other as well:

 

ping 10.254.254.3
10.254.254.3 is alive, time = 12 ms

ping 10.254.254.2
10.254.254.2 is alive, time = 2 ms

 

so far so good. But now comes the strange thing, i cant ping other IPs from Switch2 10.254.254.3:

 

ping 172.16.100.1
The destination address is unreachable.

 

but this IP is reachable from Switch1 10.254.254.2

 

ping 172.16.100.1
172.16.100.1 is alive, time = 3 ms

also, i can ping 10.254.254.2 from server 172.16.100.1:

 

 

ping 10.254.254.2

Pinging 10.254.254.2 with 32 bytes of data:
Reply from 10.254.254.2: bytes=32 time<1ms TTL=253
Reply from 10.254.254.2: bytes=32 time<1ms TTL=254
Reply from 10.254.254.2: bytes=32 time<1ms TTL=254
Reply from 10.254.254.2: bytes=32 time<1ms TTL=254

but cant ping 10.254.254.3 from 172.16.100.1

 

 

>ping 10.254.254.3

Pinging 10.254.254.3 with 32 bytes of data:
Request timed out.
Request timed out.
Request timed out.
Request timed out.

 

there is no Firewall (or any other restriction) in between.

 

Anyone an idea what is wrong here?

Thanks a lot
