Cisco IOS 15.0(1)M

I am never one to fear something new – except perhaps a new release of a JVM.

Some weeks ago, I decided it would be a good idea to upgrade one of my home routers to IOS 15.0(1)M – seeing as I paid enough for a maintenance contract, I’m entitled.  Ever since that day, I’ve been unable to ssh to the router with an access-class applied to the VTY lines.  Every time, it refuses my connection, but allows it without an access-class.

This morning, I stumbled upon the answer – put ‘vrf-also’ at the end of the access-class line: access-class 99 in vrf-also. This only matters if you’re running VRF Lite, as I am, because I have a separate firewall and ‘clean’ and ‘dirty’ VRFs.

Never fear something that’s new – expect breakage, and expect to learn.

On The Buses

TfL’s Countdown system for London Buses was a leap forward several years ago. I can now walk up to a bus stop and tell – with reasonable accuracy – how long before my bus arrives.

There is one problem with this – I have to be at the bus stop!

When National Rail introduced Live Departure Boards several years ago, it was a giant leap forward for rail travellers. TfL brought in Live Departure Boards for the Underground some years later, although this is less useful.

Wouldn’t it be absolutely fantastic to have a map of a bus route with the positions of the buses on it? Colour the map in with a deeper shade where the route is more congested, and let people have a visual representation of how long it’s likely to take for their bus to arrive. Before you leave home, have a look to see where the delays are on your route in to work, and re-plan your journey if it’s going to take too long.
