From 56a2bed46bf7713cd773b0fd0c097bcfc6345cc1 Mon Sep 17 00:00:00 2001 From: Martin Mares Date: Mon, 17 Apr 2000 12:46:07 +0000 Subject: Don't import/export MED and LOCAL_PREF on external links. Added real comparison of BGP routes (inspired by the Cisco one). Default local preference and default MED are now settable. Defined filter keywords for all BGP attributes we know. --- proto/bgp/config.Y | 26 ++++++++++++++++++++++++-- 1 file changed, 24 insertions(+), 2 deletions(-) (limited to 'proto/bgp/config.Y') diff --git a/proto/bgp/config.Y b/proto/bgp/config.Y index 635c4f64..548f5d03 100644 --- a/proto/bgp/config.Y +++ b/proto/bgp/config.Y @@ -15,7 +15,9 @@ CF_HDR CF_DECLS CF_KEYWORDS(BGP, LOCAL, NEIGHBOR, AS, HOLD, TIME, CONNECT, RETRY, KEEPALIVE, - MULTIHOP, STARTUP, VIA, NEXT, HOP, SELF, BGP_PATH) + MULTIHOP, STARTUP, VIA, NEXT, HOP, SELF, DEFAULT, PATH, METRIC, + BGP_PATH, BGP_LOCAL_PREF, BGP_MED, BGP_ORIGIN, BGP_NEXT_HOP, + BGP_ATOMIC_AGGR, BGP_AGGREGATOR, BGP_COMMUNITY) CF_GRAMMAR @@ -27,6 +29,8 @@ bgp_proto_start: proto_start BGP { BGP_CFG->hold_time = 240; BGP_CFG->connect_retry_time = 120; BGP_CFG->initial_hold_time = 240; + BGP_CFG->default_med = ~0; + BGP_CFG->compare_path_lengths = 1; } ; @@ -48,9 +52,27 @@ bgp_proto: | bgp_proto KEEPALIVE TIME NUM ';' { BGP_CFG->connect_retry_time = $4; } | bgp_proto MULTIHOP NUM VIA IPA ';' { BGP_CFG->multihop = $3; BGP_CFG->multihop_via = $5; } | bgp_proto NEXT HOP SELF ';' { BGP_CFG->next_hop_self = 1; } + | bgp_proto PATH METRIC NUM ';' { BGP_CFG->compare_path_lengths = $4; } + | bgp_proto DEFAULT BGP_MED NUM ';' { BGP_CFG->default_med = $4; } + | bgp_proto DEFAULT BGP_LOCAL_PREF NUM ';' { BGP_CFG->default_local_pref = $4; } ; -CF_ADDTO(dynamic_attr, BGP_PATH { $$ = f_new_dynamic_attr(EAF_TYPE_AS_PATH, T_PATH, EA_CODE(EAP_BGP, BA_AS_PATH)); }) +CF_ADDTO(dynamic_attr, BGP_PATH + { $$ = f_new_dynamic_attr(EAF_TYPE_AS_PATH, T_PATH, EA_CODE(EAP_BGP, BA_AS_PATH)); }) +CF_ADDTO(dynamic_attr, BGP_LOCAL_PREF + { $$ = f_new_dynamic_attr(EAF_TYPE_INT, T_INT, EA_CODE(EAP_BGP, BA_LOCAL_PREF)); }) +CF_ADDTO(dynamic_attr, BGP_MED + { $$ = f_new_dynamic_attr(EAF_TYPE_INT, T_INT, EA_CODE(EAP_BGP, BA_MULTI_EXIT_DISC)); }) +CF_ADDTO(dynamic_attr, BGP_ORIGIN + { $$ = f_new_dynamic_attr(EAF_TYPE_INT, T_INT, EA_CODE(EAP_BGP, BA_ORIGIN)); }) +CF_ADDTO(dynamic_attr, BGP_NEXT_HOP + { $$ = f_new_dynamic_attr(EAF_TYPE_IP_ADDRESS, T_IP, EA_CODE(EAP_BGP, BA_NEXT_HOP)); }) +CF_ADDTO(dynamic_attr, BGP_ATOMIC_AGGR + { $$ = f_new_dynamic_attr(EAF_TYPE_OPAQUE, T_ENUM_EMPTY, EA_CODE(EAP_BGP, BA_ATOMIC_AGGR)); }) +CF_ADDTO(dynamic_attr, BGP_AGGREGATOR + { $$ = f_new_dynamic_attr(EAF_TYPE_INT, T_INT, EA_CODE(EAP_BGP, BA_AGGREGATOR)); }) +CF_ADDTO(dynamic_attr, BGP_COMMUNITY + { $$ = f_new_dynamic_attr(EAF_TYPE_INT_SET, T_CLIST, EA_CODE(EAP_BGP, BA_COMMUNITY)); }) CF_CODE -- cgit v1.2.3
