MPBGP is not specifically linked to MPLS, there are others to. You can do CLNS, vpnv4 (unicast), ipv4 (unicast (the default), multicast, vrf), ipv6 (multicast, unicast), etc.
Check out RFC2858 for more info http://www.ietf.org/rfc/rfc2858.txt The whole MPBGP thingy can get confusing but the VPNv4 routes are really just IPv4 routes with an RD prepended, this is from Cisco: "VPNv4 routes are the same as IPv4 routes, but VPNv4 routes have a route descriptor (RD) prepended that allows replication of prefixes" http://www.cisco.com/en/US/docs/ios/iproute_bgp/configuration/guide/irg_overview_ps6441_TSD_Products_Configuration_Guide_Chapter.html#wp1054259 Check out the DocCD for more info: http://www.cisco.com/en/US/docs/ios/iproute_bgp/configuration/guide/irg_basic_net.html HTH Thank you, Steve Di Bias Network Engineer - Information Systems Valley Health System - Las Vegas Office - 702- 369-7594 Cell - 702-241-1801 [email protected] -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Poonam Sent: Monday, June 27, 2011 6:15 AM To: [email protected] IE Subject: [OSL | CCIE_RS] vpnv4 address families Question; Do you always setup vpnv4 address family when configuring MP-bgp, no matter the protocol running over it ? and is MP-bgp explicitly linked to MPLS ? it all seems to mesh with one another, i.e. we almost always seem to use mpls vpn's in conjunction with mp-bgp. in the previous labs i was doing it seemed as the vpnv4 'carried' the VRF information. rgds, Alef _______________________________________________ For more information regarding industry leading CCIE Lab training, please visit www.ipexpert.com Are you a CCNP or CCIE and looking for a job?
