Hi there! Once again, let`s discuss VPN and MTU What we have? Ethernet LAN, L2TP to ISP and IPSec with AES crypto in tunnel mode. So protocols overhead is 40+73 bytes (L2TP + ESP). What is the best way to avoid fragmentation for all IP protocols on ...

Hello! Please help: we have 2 routers, 2 areas (0 and 10) and only one 10G link between them. Right now this link belong to area 0, so area 10 is discontigous.What is the right solution for this situation?

Hello! Please help me to understand debug output (file attached). Interface Virtual-ppp1 gets up for 1 minute, no traffic can pass through and then interfaces goes down. I am trying to investigate the cause.

Please tell me what are guidelines of configuring ipsec on a single interface. It would be nice to hear your success stories and see some working examples.Thanks!

What is the best way to set MTU? Choices are: Fe4 (WAN), Virtual-PPP1 (L2TP session interface) or Vlan1 (LAN).

Lests start again:We have to sites, A and B, we need layer 2 between them because server A and server B must be in single L2 domain, so we use L2 trunk and HSRP to reserve gateway.Site C have L3 connections with A and B, and we use OSPF for dynamic r...

You are correct except one moment - vlan 10 is ospf passive interface and switches are making neighborship only using single interface belonging to area 0.

HSRP is needed by servers that must be placed in single L2 domain

All switches are at different locations, so if switch A goes down, all hosts on this DC are unaccessible, and traffic flows must be rerouted to backup DC (B)
