I am implementing a Metro solution where I have two 7600s that are connected through an MPLS backbone. These 7600s have a point-to-point EoMPLS VC between them. NOTE: The 7600s do not have an OSM card, they are using the Sup720 ports to create de VC.
The 7600s are connected to the Metro Ethernet ring using an Etherchannel with two ports bundled.
Evrything is working ok, but sometimes the EoMPLS VC stop passing multicast traffic. The customer can send pings BUT their EIGRP (18.104.22.168) routing between the CPEs is down.
Well, my configuration is a little bit different: I am doing PFC-based EoMPLS (without OSM), so I am doing the "xconnect" on a dot1q subinterface, not on a interface VLAN, and the VLANs area allowed on the trunks, BUT this problem appears when we have some outage on the network, like a backbone link flap or a crash (reload) on a PE-AGG (cat3550) connected to our 7600.
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?
