## AI overview

This article examines route redistribution on Cisco IOS/XR, showing that OSPFv2/OSPFv3, IS-IS, and BGP use inconsistent syntax for the source protocol in redistribute commands. The inconsistencies make reusable configuration templates more difficult to create.

## Source excerpt

One would hope that the developers of a network operating system wouldn't feel the irresistible urge to reinvent what should have been a common configuration feature for every routing protocol. Alas, the IOS/XR developers failed to get that memo. I decided to implement route redistribution (known as route import in netlab) for OSPFv2/OSPFv3, IS-IS, and BGP on IOS/XR (Cisco 8000v running IOS/XR release 24.4.1) and found that each routing protocol uses a different syntax for the source routing protocol part of the redistribute command.
