See for instance

- PDF page 41 (slide 82) from Networkers 2001 session "Deploying BGP for
Enterprises and ISPs",

http://www.cisco.com/networkers/nw01/pres/pr/ps_presos/PS_545_TURNER_C2.pdf

- PDF page 27 and 28 (slide 54 and 55) from Networkers 2004 session
"Deployment and analysis of BGP",

http://www.cisco.com/networkers/nw04/presos/docs/RST-2303.pdf

I have no idea why they haven't changed the IOS XR defaults. I know all
*our* IOS XR speaking routers are using a distance of 200 for both
iBGP and eBGP, on Cisco's recommendations.
