Frame relay: Multilink point to point frame relay

Reference: http://www.cisco.com/en/US/docs/ios/12_2s/feature/guide/fs_mfr.html Multilink Frame Relay (FRF.16.1) 1. This technology aggregates multiple number of physical serial interfaces into one bundle. a. This provides link redundancy i.e. if a physical link of a bundle has failed, the frame relay link will still be available. b. This also provides bandwidth aggregation from multiple serial interfaces. (See http://www.cisco.com/en/US/docs/ios/12_2s/feature/guide/fs_mfr.html#wp1054102) 2. The aggregated … Continue reading Frame relay: Multilink point to point frame relay

Connecting Enterprise hub to other enterprise spokes over NBMA (frame-relay)

The original design intention is not to advertise routes using ospf over NBMA network, it is not necessary for this case. However for Buona Vista HQ to be able to reach the two sites, I need entries in the routing table to let other routers know the road map to reach. A way is to … Continue reading Connecting Enterprise hub to other enterprise spokes over NBMA (frame-relay)
