I'm having trouble getting a link up between two sites on new ENS circuits. I have tested connectivity by plugging in the Ciena ethernet handoff to a switch at a location, and then at another location plugging a laptop into the Ciena there, and low and behold I get DHCP from the remote site and I'm on that remote sites network as if I were there.
Ok so basic connectivity test ok. Now for the real purpose. Plugging in the ciena's at each location into Cisco 2811 routers, I have them set to auto negotiate speed and duplex. But for each router I am specifying a sub interface with 802.1q tagging, basically one is a LAN for VOIP traffic and one is for regular DATA traffic each with their own QoS policy map.
Now I cannot seem to get the routers to ping each other sourced from either lan. I can SSH to the remote router via cellular connection from the main router and things seem to be jiving config wise.
I know using 802.1q adds a little bit of overhead to the packet size, so do you think this could be an MTU issue? Our welcome kit says ENS MTU is 1600 which should be more than enough for 1522 frame size after adding 802.1q.
Other concerns is that this is across two markets. The network diagram shows after leaving a Cisco switch in one headend, it heads to "ibone" and then into a Juniper switch in another headend. So I am wondering if anywhere along that path there is something blocking this.
