From 7eb5b47e54169ac0da40ed1a6760db5d5f915a4d Mon Sep 17 00:00:00 2001 From: Paul Jakma Date: Tue, 13 Oct 2009 16:13:13 +0100 Subject: ospfd: Remember network LSA sequence numbers across up/downs of an interface * ospf_interface.h: (struct ospf_if_params) add field for saved network LSA seqnum * ospf_interfa.c: (ospf_new_if_params) init network_lsa_seqnum field to initial seqnum - doesnt matter though. * ospf_lsa.c: (ospf_network_lsa_new) check for any saved sequence number, and use if it exists. Save the result back. This should help avoid needless round of LSUpdate/LSRequests when a neighbour has to tell the originator "uhm, i have something newer than that already". * ospf_vty.c: (show_ip_ospf_interface_sub) Show the saved network LSA seqnum --- ospfd/ospf_vty.c | 8 +++++++- 1 file changed, 7 insertions(+), 1 deletion(-) (limited to 'ospfd/ospf_vty.c') diff --git a/ospfd/ospf_vty.c b/ospfd/ospf_vty.c index adc822a7..4e52a113 100644 --- a/ospfd/ospf_vty.c +++ b/ospfd/ospf_vty.c @@ -2933,7 +2933,13 @@ show_ip_ospf_interface_sub (struct vty *vty, struct ospf *ospf, inet_ntoa (nbr->address.u.prefix4), VTY_NEWLINE); } } - + + /* Next network-LSA sequence number we'll use, if we're elected DR */ + if (oi->params && ntohl (oi->params->network_lsa_seqnum) + != OSPF_INITIAL_SEQUENCE_NUMBER) + vty_out (vty, " Saved Network-LSA sequence number 0x%x%s", + ntohl (oi->params->network_lsa_seqnum), VTY_NEWLINE); + vty_out (vty, " Multicast group memberships:"); if (OI_MEMBER_CHECK(oi, MEMBER_ALLROUTERS) || OI_MEMBER_CHECK(oi, MEMBER_DROUTERS)) -- cgit v1.2.1
