Let's say you have a non-MPLS backbone in which you have two PE routers(maybe it doesn't fit the traditional PE definition, but let's call then customer-facing routers). You have a MP-GP session between the two PEs advertising prefixes and VPN labels.
If you configure GRE tunnel or L2TPv3 tunnel with no LDP over them between the two PEs and make sure that Loopback interfaces (next_hop attribute) are available through the tunnels, will it be possibe to send the traffic and maintain connectivity for VPN customers?
In this case the packet within the backbone would look like (in GRE case):
IP is the outer IP header for GRE tunnel endpoints.
GRE will also need to support MPLS in "Protocol Type" field in GRE header, which I suppose it does...
With XR 4.2.0 the ASR9000 is releasing a new line of hardware models. This amongst others is the RSP440, the next generation RSP with faster switch fabric along with Typhoon based Linecards, the next generation network processor.
The Cisco EPN system incorporates a network architecture designed to consolidate multiples services on a single Multiprotocol Label Switching (MPLS) transport network. This network is designed primarily based on...
Internet security is important with the increasing attacks that are happening every day. Many internet and browsing security solutions exist, but some are not very easy to use or maybe the question is how can I enable them?
