Hi Alok, it is recommend but not necessary to have an area 0. Have a look at http://www.ietf.cnri.reston.va.us/internet-drafts/draft-rosen-vpns-ospf-bgp- mpls-06.txt to get an better impression about the problems of OSPF in a MPLS-VPN environment. regards ------------------------------------------------------------ Carsten Strahler IP Planning Lambdanet Communications Deutschland AG (AS 13237) Guenther-Wagner-Allee 13 D-30177 Hannover (Germany) Phone +49 (0)511 / 84 88 12 57 Mobile +49 (0)173 / 629 1257 Fax +49 (0)511 / 84 88 12 59 mailto:carsten.strahler@lambdanet.net web: www.lambdanet.net ----------------------------------------------------------- > -----Ursprungliche Nachricht----- > Von: Alok Dube [mailto:alokdube1978@rediffmail.com] > Gesendet: Freitag, 25.
