Lab 131 - BGP Next-Hop using Redistribution into IGP

Prerequisites: CCNP level skills.

Note!
Use the configuration from Lab 130 except for route-maps that change the next-hop.

Task 1
Similarly to the lab 129 and 130, deal with the next hop on R1, R2 and R3, but do not use 'next-hop-self' or route-map to change the next-hop while advertising BGP prefixes in AS 123.
