Suppose company A has a PA allocation 10.21.0.0/20. Company A gets a T1 from Carrier B. Carrier B announces 10.21.0.0/20 with their AS65531 and statically route the /20 to company A. If Company A wants to be redundant and gets another T1 from Carrier C, Carrier C will announce 10.21.0.0/20 with their AS65532 and statically route 10.21.0.0/20 to Company A.
I see no problem in this. If Carrier B screws up, the traffic will still flow through Carrier C. If Carrier B screws up in such a way that they still announce the netspace, Carrier C can announce 2 /21's instead of 1 /20 so it will still work.
This isn't being done. Only one AS is announcing the route. The other registration is cruft.
