Hello Group,
For those who have done this very good lab.
R2--------R5-------
\ |

\ R3-E0 150.1.30.3/24
\ |

R1-----R4----------
R3 has an network on its Ethernet interface that is injected into OSPF as an
external route.
This route [via R5] is then redistributed on R2 into EIGRP 100 and carried
across the tunnel to R4, where if the administrative distance of the R3-R4
(ospf) path is raised to 171 the R3 E0 route via R5-R2-R4 is passed on to
R1.
The same R3 E0 route is also redistributed on R4 from OSPF into RIP and then
from RIP into EIGRP. The route is successfully redistributed into RIP but
not from RIP into EIGRP.
The only relevant config appears to be R4
So my questions are
1) Why is the RIP to EIGRP redistribution not working [as expected]?
2) and hence how does one achieve a redundant path to this route. ie in
case of R2-R4 tunnel failure?
