The expected prefix should be 5.5.5.0/24 otherwise the hosts behind NHRP client 1 nhc1 (aka. r5) are not reachable via NHRP. The issue was not seen in the FRR official CI because the tests were skipped because iptables were missing in CI machines. It solves the 16690 issue. Fixes: FRRouting#16690 Signed-off-by: Louis Scalbert <[email protected]>

Rename router variables in nhrp_redundancy to match the actual name. Cosmetic change to help debugging. Signed-off-by: Louis Scalbert <[email protected]>
Simplify nhrp_redundancy convergence code. Cosmetic change. Signed-off-by: Louis Scalbert <[email protected]>
After setting down nhs1, the test is checking that nhc1 routing table matches routes in nhc1/nhrp_route.json. It is incorrect because it checks that the NHRP route to nhs1 is still present but it should have disappeared. Signed-off-by: Louis Scalbert <[email protected]>
Fully check the NHRP convergence after setting nhs1 down. Otherwise the ping may pass because the previous shortcut is still present. Signed-off-by: Louis Scalbert <[email protected]>
