Hi, I'm trying to establish a trunk between SSG20 and Cisco 2950. I have a trunk port on my cisco allowing VLANs 100,990.
My subinterfaces on the Juniper are:
set zone id 109 "VLAN990" set zone id 100 "VLAN100" set interface ethernet0/4.1 tag 100 zone "VLAN100" set interface ethernet0/4.1 ip 10.10.10.1/24 set interface ethernet0/4.1 route set interface ethernet0/4.2 tag 990 zone "VLAN990" set interface ethernet0/4.2 ip 172.30.0.1/23 set interface ethernet0/4.2 route However, the trunk doesn't appear to be working as I can't PING IPs on the either side of the network, i.e from Juniper I can't see IPs on the Cisco side and vice versa.
You interface tagging configuration looks correct. But I don't see any policies setup for your two associated zones. If you are not sourcing the ping from the same zone to the same zone it will be blocked without a policy setup for it. You will need to create the trust to vlan100 or vlan990 policy to allow the traffic.
