Alternate to IRINN IRR manual entry / ALTDB

Anurag Bhatia
IRINN (Indian Registry for Internet Names and Numbers) is a NIR (National Internet Registry) for India operating under the APNIC RIR (Regional Internet Registry). IRINN is run and managed by NIXI. It’s a decent NIR and was set up in 2012. Indian organisations have the option to either maintain relation with APNIC or with IRINN. A large number of small networks prefer IRINN because it’s annual charges are 25000 INR / $351 USD against APNIC’s membership fee which is over 2x of that.

BGP Administrative Shutdown Communication

Anurag Bhatia
I recently came across an excellent draft at IETF by Job Snijders & friends. This is to address scenarios where a network might miss communication about a maintenance activity when BGP shutdown happens. Once implemented, this can potentially offer to send peer a message with up to 128 bytes with info about shutdown like “Ticket XXX: We are upgrading the router, will be back live in 1hr” etc. It depends by appending such data to the sys notification which is part of BGP protocol.

Route filter generation for Mikrotik RouterOS via IRR

Anurag Bhatia
A while back I posted about routing filter generation via bgpq3 for Cisco (ios and XR) and Juniper JunOS based routers. I have received a number of emails in last few months about automated filter generation for Mikrotik routeros. Since Mikrotik’s CCRs are getting quite popular across small to mid-sized ISPs. So this blog post is about ways for generating filter config for a given ASN via IRR. One can use such logic with some kind of remote login mechanism like rancid (look for mtlogin here).

Peering with content networks in India

Anurag Bhatia
One of frequent email and contact form message I get my blog is about available content networks in India and where one can peer. There are certain content networks in India and of course most of the content networks have open peering policy and are usually happy with direct inter-connection (we call as “peering”) with the ISP networks (often referred to as “eyeball networks”). Some of these networks have a backbone which connects back to their key datacenter locations on their own circuits via Singapore/Europe, some other have simply placed their caching server where cache fill happens over IP transit.
