I'm working for an ISP. Since our clients often ask for testing performance on dsl and sdh links in the mpls cloud and I didn't found a method at work except IP SLAs udp jitter operation -which is quite useful, but not realistic-, I started using ttcp.
It only works on the CE -> PE uplink as it seems not to support vrf.
It could also work from a backbone router which imports loopback ip management addresses through bgp from every client for the backbone -> CE downlink.
TTCP isn't unique to Cisco, documentation for it can be found on the web.
One problem with TTCP on Cisco routers, most(?) IOS images don't have it. (More likely on service provider images?) Second problem, I found it often can't stress bandwidth except on smaller links. (The stats for drops/retransmits is good though, if provided.)
You can obtain PC versions of TTCP. I like the DOS PCATTCP which also supports UDP tests.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
