Hi,
I configured an ERS 4950 as usual and it's not the first time that I did it. but this one is not responding to icmp resquests. this switch can ping all other spbm configured switches. but it can not ping VSP (containing VRRP configurtion) ans non spbm Switches. can you help me ?
Regards,

IP reachablilty is usually just a misconfiguration somewhere.
On switch 1 make sure you set your mgmt vlan. Did you set a IP DEFAULT GW?

hello,
mgmt vlan is ok (I use default one 1)
I put this line : ip address stack 10.xx.xx.xx net mask 255.225.255.0 default-gateway 10..xx.xx.254
I did other tests :
- install the stack without spbm, I configure only ip stack, netmask and default gateway --> OK
- I active spbm, after reboot, no ping
- add spbm configuration --> no ping

Hi,
Thanks for your answer. here are different connexions :
on SW1 :
ping all VSP --> non OK
ping SW2 --> OK
ping SW3 (non spbm) --> non OK
ping gateway --> non OK
ping other VLANs --> non OK
show isis adjacencies : VSP1 (with the right interfaces)
show autotopology nmm-table : VSP1 (with the right interfaces)
on VSP1 :
ping SW1 --> ok
ssh SW1 --> ok
spbm adegencies --> contains SW1
SW1 is not on ping from and to other VLANs, no response when I ping it's gateway.
on SW2 :
ping SW1 --> OK
ssh SW1 --> OK

Hello Hatem,
Which IP address are you trying to reach ?
What is the idea behind the loopback configuration ?
If you try to reach the loopback, you need to activate "ip routing" (not present in shared config) and add a default route to mgmt vlan gateway (will be used after the ip routing activation).
