Hi Guys
our backbone runs on standard wireless( no NSTREME) and mpls ldp
using default config for all the mpls and ospf/bgp routing,
I started putting more of the backbone onto mpls cloud to give more layer 3 vpns
when i telnet into the routers, I do ip route print and the terminal freezes, I can telnet in again and do small things , but as soon as I print the big routing table it freezes, from my expierence this is MTU issues where fragmentation is happening, I dont have any clients complaining as our backbones is running around 60mbit and still does
i added a MSS forward rule on of the ABR router where i come in and it solves my problem
/ ip firewall mangle add chain=forward protocol=tcp tcp-flags=syn action=change-mss new-mss=1450
Does this mean mpls is causing fragementation to happen on the switching of packets?
mpls ldp interface print has mtu of 1508 and my default ethernet and wlan devices is 1500
Any advice would be appreciated
Thanks
S
