The link is terminated on 2950's(Trunk Ports) at each end, with the 2950's then connected(Also trunk ports) to 7204VXRs, and the various vlans broken out into dot1q Ints. Without MPLS(Including MPLS L3 VPNs) running on the link, we can access all WebSites without issue - As soon as MPLS is enabled, some sites are not accessible(https sites, www.smh.com.au...) If we switch back to our primary link(ATM), we also do not experience any mtu issues. Should we be decreasing the size of mpls mtu on the 7200's? Thanks in advance for all suggestions. ------------------------------------------------------------------------- This e-mail was sent via Data FX Online WebMail http://www.datafx.com.au/ _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/ _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
