From dkalo at noc.ntua.gr Tue Feb 15 16:38:39 2005 From: dkalo at noc.ntua.gr (Dimitrios Kalogeras) Date: Tue, 15 Feb 2005 17:38:39 +0200 Subject: IRRtoolset 4.8.2 and RPSLng Message-ID: <4212177F.4010808@noc.ntua.gr> Hi to all of you, I apologize for the cross posting but I believe this is of interest to all of you. We have noticed some problems with the IRRtoolset regarding the interpretation of RPSLng from RtConfig. The command used for Rtconfig is : RtConfig -h whois.ripe.net -p 43 -protocol ripe -cisco_use_prefix_lists A small template used for RtConfig was : @RtConfig set cisco_map_first_no = 10 @RtConfig set cisco_map_increment_by = 10 @RtConfig set cisco_max_preference = 220 ! Parameters @RtConfig set cisco_prefix_acl_no = 130 @RtConfig set cisco_aspath_acl_no = 130 @RtConfig set cisco_pktfilter_acl_no = 130 @RtConfig set cisco_community_acl_no = 130 @RtConfig set cisco_access_list_no = 130 ! ***** Specify each peer's incoming filter **** ! GEANT @RtConfig set cisco_map_name = "bgp-geant-%d-%d-in" @RtConfig import AS5408 195.251.27.255 AS20965 62.40.103.57 @RtConfig set cisco_map_name = "bgp-geant-%d-%d-out" @RtConfig export AS5408 195.251.27.255 AS20965 62.40.103.57 @RtConfig set cisco_map_name = "bgp-geant-bkp-%d-%d-in" @RtConfig import AS5408 195.251.27.255 AS20965 62.40.103.201 @RtConfig set cisco_map_name = "bgp-geant-bkp-%d-%d-out" @RtConfig export AS5408 195.251.27.255 AS20965 62.40.103.201 Problems: a) In lines with mp-import and afi ipv4.unicast there is error generation although the RIPE RPSLng accepts the object !!! In some cases if we download the object and execute the RtConfig -h whois.ripe.net -p 43 -protocol ripe -cisco_use_prefix_lists -f < saved object there is no problem !!! b) When we use the switch -cisco_eliminate_dup_map_parts the result is wrong when the policy has multiple address_families defined. c) It is not possible to generate route-maps when the template have IPv6 address like " @RtConfig export AS5408 2001:648:2FFF:1:: AS20965 2001:798:2017:10AA::1 if in the RIPE as object we have defined our on IPv6 attachment point. Instead to in order to generate IPv6 route maps we define @RtConfig export AS5408 195.251.27.255 AS20965 2001:798:2017:10AA::1 int the RtConfig templates !!! This results in Ipv6 route-maps generated !! d) The RPSLng robot of RIPE is broken. We intentionally provide a wrong object and the RIPE robot passed it without a problem !!!
