Sun Oct 06, 2019 1:22 am

Hi Im having a Issue from 3 months ago could not resolve it and had searched on the web without any clue.
I have the following topology

Need to activate MPLS on the network for giving customers services like l3 vpn.

My problem is that when I have a customer from site 78 via a wireless link and I activate LDP on Site 80 every https / http downloads cancels giving out the error "Network Error"
I have notice that when I disable there's not issue whith downloads any single.

Running ROS: 6.44.5

From Site 80 I have OSPF to other sites I have
I have enabled Jumbo Frame on PTP links, Checked the Switch Configurations and MTU are set to 9216 on the switches.

here are some ss from the configurations
Site 80

Typically the issue you are describing indicates a problem with MTU somewhere.

What are your MTU settings for.

L2
L3
MPLS

L2 MTU: 1580
MPLS MTU: 1530

On the vlan Is has
L3 MTU: 1500
L2 MTU(Autoconfigure to): 1576

AirFiber: JumboFramce Activated on both PTP

Site 1 Edgepoint S16: MTU on all interfaces 9216

The first thing I would do is connect a router locally to Site 80 that isn't over the wireless link, enable MPLS and see i it's still an issue.

Does this hapen to all HTTP/HTTPs sites or only some of them?
