From 907fd95e502e10334e5390c73cc57588b88b8171 Mon Sep 17 00:00:00 2001 From: Peter Szilagyi Date: Sat, 1 Oct 2011 17:15:46 +0400 Subject: isisd: send proper LSP after DIS election After an IS has been elected as the Designated IS for a LAN, it did not refresh the content of the pseudo-node after a new node has been connected to the same LAN. Instead, the periodically reoriginated pseudo-node LSP still contained only those IS neighbors that were already present when the DIS election process was commenced. The fix for the problem schedules an LSP regeneration rather than just reoriginating the same LSP with the old content.
