We only provide layer 2 connectivity. ISPs on NZIX don't have to follow some certain routing protocol. It should depend on their interest. But it should be said that Kawaihiko had multiple service providers and NZIX was the place where most of domestic traffic got exchanged. It's why Waikato has used OSPF to collect NZ routes from NZIX. Since Kawaihiko network broke up, we have been trying to build a new way to meter traffic. It will be appreciated very much if Clear can keep OSPF running until we have rolled out the new metering system.

IOS configuration lint script

by Joe Abley

[This message has also been posted.] Hi, At various times I have been involved in maintaining routers with lots of (sub)interfaces, and lots of static routes pointing down those subinterfaces. Unfortunately, a simple "show run" on a router produces a listing with all the static routes listed together, and all the subinterfaces listed separately. On a router with a lot of static routes and a lot of connected networks, this becomes a bit of a headache - you end up with static routes hanging around long after the subinterface has been removed, and spring cleaning usually results at least a couple of confused and unhappy users for whom inbound traffic is now spiralling off somewhere else. Even when this kind of configuration is made automatically (from a database which enforces referential integrity), the odd quick-fix static route added at some time might well hang around for years after it has stopped being useful. I have often wished that I could do a "show run" which would group IOS configuration by customer. Now I can! Hooray! Take an IOS configuration file (as tftp'd or rsh'd somewhere, or perhaps retrieved using ciscoconfd) and pass it through this awk script. The configuration will be re-sorted, so that: + most configuration comes first + (sub)interface configuration comes next, with corresponding static routes + all other static routes come next + "end" The static routes corresponding to a connected (sub)interface are hence shown grouped with that subinterface. All static routes that don't point at a connected network are listed separately right at the end, where they can be scruitinised and (if appropriate) removed. Example: The following stripped-down configuration: version 11.1 service timestamps log datetime localtime service password-encryption no service udp-small-servers no service tcp-small-servers ! hostname eg ! clock timezone NZST 12 clock summer-time NZDT recurring 1 Sun Oct 2:00 3 Sun Mar 2:00 enable secret 5 hohoho ! interface ATM5/0 mtu 1500 no ip address no ip route-cache optimum atm ilmi-keepalive 30 atm pvc 999 0 16 ilmi ! interface ATM5/0.2 point-to-point description customer1's network ip address 192.168.24.1 255.255.255.252 atm pvc 502 2 120 aal5snap inarp ! interface ATM5/0.3 point-to-point description customer2's network ip address 192.168.24.5 255.255.255.252 atm pvc 503 2 51 aal5snap inarp ! interface ATM5/0.4 point-to-point description customer3's network ip address 192.168.24.9 255.255.255.252 atm pvc 504 2 52 aal5snap inarp ! interface ATM5/0.5 point-to-point description customer4's network ip address 192.168.24.13 255.255.255.252 atm pvc 505 2 53 aal5snap inarp ! ip name-server 203.97.33.1 ip name-server 203.97.37.1 ip classless ip route 10.1.4.0 255.255.252.0 192.168.24.14 ip route 172.16.0.0 255.255.0.0 192.168.24.6 ip route 172.18.0.0 255.255.0.0 192.168.24.2 ip route 192.168.25.0 255.255.255.0 192.168.24.14 ip route 192.168.27.0 255.255.255.0 192.168.24.42 ! line con 0 exec-timeout 0 0 length 20 line aux 0 line vty 0 4 exec-timeout 0 0 password 7 humhumhum length 25 ! end When run through ios-lint.awk, we get: ! generated by cisco_lint.awk ! version 11.1 service timestamps log datetime localtime service password-encryption no service udp-small-servers no service tcp-small-servers ! hostname eg ! clock timezone NZST 12 clock summer-time NZDT recurring 1 Sun Oct 2:00 3 Sun Mar 2:00 enable secret 5 hohoho ! ip name-server 203.97.33.1 ip name-server 203.97.37.1 ip classless ! line con 0 exec-timeout 0 0 length 20 line aux 0 line vty 0 4 exec-timeout 0 0 password 7 humhumhum length 25 ! interface ATM5/0 mtu 1500 no ip address no ip route-cache optimum atm ilmi-keepalive 30 atm pvc 999 0 16 ilmi ! interface ATM5/0.2 point-to-point description customer1's network ip address 192.168.24.1 255.255.255.252 atm pvc 502 2 120 aal5snap inarp ! ip route 172.18.0.0 255.255.0.0 192.168.24.2 ! interface ATM5/0.3 point-to-point description customer2's network ip address 192.168.24.5 255.255.255.252 atm pvc 503 2 51 aal5snap inarp ! ip route 172.16.0.0 255.255.0.0 192.168.24.6 ! interface ATM5/0.4 point-to-point description customer3's network ip address 192.168.24.9 255.255.255.252 atm pvc 504 2 52 aal5snap inarp ! interface ATM5/0.5 point-to-point description customer4's network ip address 192.168.24.13 255.255.255.252 atm pvc 505 2 53 aal5snap inarp ! ip route 10.1.4.0 255.255.252.0 192.168.24.14 ip route 192.168.25.0 255.255.255.0 192.168.24.14 ! ! !

RE: BGP over NZIX

Hi Felix Your email implies that you are waiting only for Waikato to implement BGP at NZIX. This does not appear to be a fair call, as no one else on the mailing list that Joe Abley posted to has made any comment on whether they would BGP peer or not at NZIX and especially the largest ISP in NZ Telecom.

For our customers we apply community tags to routes so that customers can differentiate between routes learnt from off-shore BGP peers, and those learnt from within NZ - I would imagine that Telecom can do something similar for you. I would keen to hear Telecom NZ view as they seem to have been very quiet on this topic?

BGP over NZIX -comments from Waikato about Joe Ableys posting on this topic

by Warwick GLENDENNING

Waikato has no objection to carriers or ISP's running BGP meshes at the NZIX if it provides a more robust service. However from Waikato's perspective (and possibly for other smaller NZIX users) we would prefer that routers connected to the NZIX also ran OSPF as we use this process to collect NZ routes and differentiate between domestic and international traffic for our campus IP traffic metering.It is possible that other NZIX users do the same. OSPF is also less complex to manage for smaller users with fewer highly skilled network staff.
