  • 1.  IPv6 implementation

    Posted 11-11-2008 02:04
    We are implementing IPv6 within the internal network.  What would you recommend to use for IGP.  currently using OSPFv2 for IPv4 network.  Will there be a problem to use both OSPFv2(IPv4) and OSPFv3(IPv6) simultaneously?  What about ISIS for ipv6?  We are using juniper m20s.

    Hi,

    In my opinion,

    it s recomanded to use ISIS since this protocole is extensible and thre is no differnces beteen IPv6 and IPv4 for ISIS,

    only TLV's. and there is no limitation of Area 0 that ospf use it to interconnect different areas.

    Hi Cyke,

     

    It is perfectly OK to use both OSPFv2 (for IPv4 NLRI) and OSPFv3 (for IPv6 NLRI) at the same time.  However, it is remarkable how different OSPFv3 turned out from OSPFv2, given they share the same name.  If it is not too painful to convert to IS-IS, then there is a lot to be said for the extensibility of IS-IS.  It would be easier to subsequently add IPv6 to an existing network running IS-IS (as mentioned by the other poster).

     

    Rgds,
