second who to solve RIB
a week dealing with is dilemma but I failllllllllllllllllllllllllllllllllllllllllllllll llllllllll
thank you
OK i faced this problem for long period:
1) put next-hop-self in R4 for both R1 and R5
2) when you make ping use extended ping i mean:
ping
ip protocol:
Destination address: 5.5.5.5
extend: yes
source address:1.1.1.1
make sure before ping you advertised 1.1.1.1
it will work fine
For the RIP problem i think you have static route for the same destination your advertised by bgp so remove the static route and rip will clear
