From d69faad76584c4735911d6dbdc8b9ff672b3f763 Mon Sep 17 00:00:00 2001 From: David Ahern Date: Sun, 27 May 2018 08:09:59 -0700 Subject: [PATCH] selftests: fib_tests: Add prefix route tests with metric Add tests verifying prefix routes are inserted with expected metric. IPv6 prefix route tests TEST: Default metric [ OK ] TEST: User specified metric on first device [ OK ] TEST: User specified metric on second device [ OK ] TEST: Delete of address on first device [ OK ] TEST: Modify metric of address [ OK ] TEST: Prefix route removed on link down [ OK ] TEST: Prefix route with metric on link up [ OK ] IPv4 prefix route tests TEST: Default metric [ OK ] TEST: User specified metric on first device [ OK ] TEST: User specified metric on second device [ OK ] TEST: Delete of address on first device [ OK ] TEST: Modify metric of address [ OK ] TEST: Prefix route removed on link down [ OK ] TEST: Prefix route with metric on link up [ OK ] Signed-off-by: David Ahern Signed-off-by: David S.
