      Skills required are really fairly standard Cisco skills to CCNP level, but significant hands on experience would be a significant advantage. It’s basically a Branch network of some 100 or so sites, but of course they are all 3rd party sites. The main features used in the Extranet include:
·         IP Clear/MPLS connectivity
·         Some legacy Cellstream/Framestream
·         BGP, RIP and EIGRP routing protocols
·         Extensive use of GRE tunnels.
·         Extensive use of PBR
·         Some IPSEC
·         Some ISDN/ADSL
·         Hardware is mainly 2600, 2800, 3700 and 3800 routers plus 7200 and ASR1004s at the core.

    LAN skills are needed as there is a small LAN environment that BT manage. This is a L2 environment and not that complex, though knowledge of VLAN pruning would be desirable.
 Experience is BGP is must.
 CCNP is mandatory.
