MPLS over l2tp mtu

Thu Nov 12, 2020 7:17 am

Good day. I need to make an L2 channel from six points via the Internet. I made one router a server, the rest as clients with MRRU 1508. Configured vpls with mtu 1500, everything works. Found information that VPLS fragments better than PPP. This is true? (If true how to change the configuration)

MPLS/VPLS doesn't fragment at all. It requires you to have the actual needed L2MTU headroom.
Manages some CCR's, RB750Gr3, RB922 and wAP's

thanks. So the current scheme is optimal
