From c43ed2e48af8c787a1ebc4b648f844c44032db35 Mon Sep 17 00:00:00 2001 From: Donald Sharp Date: Fri, 12 Jun 2015 07:59:11 -0700 Subject: This patch changes BGP from only listening mode for BFD status updates to interactive mode of dynamically registering/deregistering BFD enabled peers with PTM/BFD through zebra. Peer is registered with BFD when it goes into established state and de-registers when it goes out of establish state. This patch also adds BFD multihop support for BGP. Whether a peer is multi-hop or single hop is determined internally. All IGP peers are considered as multi-hop peers. EBGP peers are considered as single hop unless configured as multi-hop. BGP BFD command enhancement to configure BFD parameters (detect multiplier, min rx and min tx). router bgp neighbor bfd Signed-off-by: Radhika Mahankali Reviewed-by: Dinesh G Dutt Reviewed-by: Vipin Kumar Reviewed-by: Kanna Rajagopal --- lib/ptm_lib.h | 49 +++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 49 insertions(+) create mode 100644 lib/ptm_lib.h (limited to 'lib/ptm_lib.h') diff --git a/lib/ptm_lib.h b/lib/ptm_lib.h new file mode 100644 index 000000000..1aa2f356f --- /dev/null +++ b/lib/ptm_lib.h @@ -0,0 +1,49 @@ +/********************************************************************* + * Copyright 2015 Cumulus Networks, LLC.
