Mikrotik IPv6 BGP

Ok,

it looks as it's working anyhow, but i need to create different instances with different router-id's to have two sessions between two routers. Doesn't matter that they are different address-families. What a pain.

The as-path filters that i filed a bug report in August about are still not fixed and it looks like, that I can't filter on IPv6 prefixes, either.

Looks like I'm going to kick this box to h*** soon and replace it with something decent. Mikrotik might be good at wireless, but in regards to routing, it doesn't look pretty.

GBLX IPv4 session live

Finally the last bit for our IPv4 transit falls into place: Our IPv4 session with Global Crossing got turned up today, immidiatly eating up traffic.

Hurricane IPv6 BGP tunnel TCY <-> FFM

As IPv6 over Level3 fell flat (PacketExchange can't deliver) and I still have no second IPv6 peer for TeleCity, I did set a second tunnel up with Hurricane Electric. That finally got set up today, lads must be a bit busy at HE.net.

So for IPv6 we've now Smart Telecom (native) and Hurricane London (tunnel) in Dangan, Galway. In TeleCity we've got GlobalCrossing (native) and Hurricane Frankfurk/Main (tunnel), Germany on top of the INEX peerings on Vlan#1.

The INEX Vlan#2 is a Mikrotik router and they still can't do IPv6 BGP without mix/match :(. I've been chasing them on that since 3.10 now, it was supposed to be fixed in 3.12 and as of 3.14 routing-test it still doesn't work, if I got the configuration right.

IPv6 and null-route

After re-organising the whole network lately, I wanted to get the null-route in place again for our IPv6 range. It's just nicer, than being looped around between two routers.

First barrier: It's not possible in Mikrotik. DOH !!! .. Well .. I raised a ticket with them on that.

Second barrier: I've added it like usual in the zebra daemon of quagga, by using "ipv6 route 2a02:278::/32 Null0". Well, so I thought. It actually does not work on Quagga 0.99.5, which reminds me, that I need to upgrade that box and then test it again.

Anyhow, we'll fix it via "ip" then. The command to archieve this is "ip route add 2a02:278::/32 dev lo"

Job done, all happy.

Blog update

People that have subscribed to my blog will notice, that suddenly things have happened. Yes, I was idle updating it for a good while and yes, I've catched up on the last 2-3 months, sort of.

Well, hopefully I'll have more time in the future to keep it up to date a bit more often.

GBLX IPv6 and eXpress peering live

Finally, it took ages to get the details for the Globalcrossing IPv6 and the eXpress peering sessions. But they are live now and we'll just have to wait for the eXpress route-servers to pick up our prefixes. That should happen in the next 24 hours.

All we are waiting on our circuit to PacketExchange is the session for IPv4 from Globalcrossing.

Anyhow, this means, that we have 3 IPv4 and 3 IPV6 transit carriers now.

INEX meeting, Dublin

Today was INEX meeting. As we're one of the newest members at the INEX, a presentation of the company was required, sort of. The talk can be found here. Unfortunately I didn't have the time to prepare it properly, it got hacked together the same morning, but well, very few people will notice the real hick-ups :).
