ESTABLISHING A MULTICAST BACKUP PATH

摘要

In one embodiment, a first device in a network determines a primary border gateway protocol (BGP) path and a secondary BGP path to a second device in the network. The first device sends requests to join a multicast label switched path (LSP) to the second device via the primary BGP path and via the secondary BGP path. The first device receives LSP traffic associated with the multicast LSP via the primary and secondary BGP paths. The first device drops the LSP traffic received via the secondary BGP path, in response to receiving the LSP traffic via the primary BGP path.

1. A method, comprising:
determining, by a first device in a network, a primary border gateway protocol (BGP) path and a secondary BGP path to a second device In the network; sending, by the first device, requests to join a multicast label switched path (LSP) to the second device via the primary BGP path and via the secondary BGP path; receiving, at the first device, LSP traffic associated with the multicast LSP via the primary and secondary BGP paths; and dropping, by the first device, the LSP traffic received via the secondary BGP path, in response to receiving the LSP traffic via the primary BGP path.
