From b4db37507635bf95161bea32b18736fc0732a9e6 Mon Sep 17 00:00:00 2001 From: sever-sever Date: Tue, 1 Jun 2021 11:30:11 +0000 Subject: tunnels: T3592: Set default TTL to 64 Set default TTL value for tunnels from 0 to 64 There are a lot of situation when default value 0 (inherit) not work properly when you have routing configuration for OSPF or BGP over the tunnels. To fix it you need explicit set TTL value other then 0. Or hardcode another value as default. --- smoketest/scripts/cli/test_interfaces_tunnel.py | 7 ++++--- 1 file changed, 4 insertions(+), 3 deletions(-) (limited to 'smoketest/scripts/cli') diff --git a/smoketest/scripts/cli/test_interfaces_tunnel.py b/smoketest/scripts/cli/test_interfaces_tunnel.py index ebb0158dc..841527d21 100755 --- a/smoketest/scripts/cli/test_interfaces_tunnel.py +++ b/smoketest/scripts/cli/test_interfaces_tunnel.py @@ -189,6 +189,7 @@ class TunnelInterfaceTest(BasicInterfaceTest.TestCase): self.cli_set(self._base_path + [interface, 'parameters', 'ip', 'no-pmtu-discovery']) self.cli_set(self._base_path + [interface, 'parameters', 'ip', 'key', gre_key]) self.cli_set(self._base_path + [interface, 'parameters', 'ip', 'tos', tos]) + self.cli_set(self._base_path + [interface, 'parameters', 'ip', 'ttl', '0']) # Check if commit is ok self.cli_commit() @@ -221,7 +222,7 @@ class TunnelInterfaceTest(BasicInterfaceTest.TestCase): self.assertEqual(encapsulation, conf['linkinfo']['info_kind']) self.assertEqual(self.local_v4, conf['linkinfo']['info_data']['local']) self.assertEqual(remote_ip4, conf['linkinfo']['info_data']['remote']) - self.assertEqual(0, conf['linkinfo']['info_data']['ttl']) + self.assertEqual(64, conf['linkinfo']['info_data']['ttl']) # Change remote ip address (inc host by 2 new_remote = inc_ip(remote_ip4, 2) @@ -258,7 +259,7 @@ class TunnelInterfaceTest(BasicInterfaceTest.TestCase): self.assertEqual(encapsulation, conf['linkinfo']['info_kind']) self.assertEqual(self.local_v4, conf['linkinfo']['info_data']['local']) self.assertEqual(remote_ip4, conf['linkinfo']['info_data']['remote']) - self.assertEqual(0, conf['linkinfo']['info_data']['ttl']) + self.assertEqual(64, conf['linkinfo']['info_data']['ttl']) self.assertEqual(f'0.0.0.{ip_key}', conf['linkinfo']['info_data']['ikey']) self.assertEqual(f'0.0.0.{ip_key}', conf['linkinfo']['info_data']['okey']) self.assertEqual(int(idx), conf['linkinfo']['info_data']['erspan_index']) @@ -314,7 +315,7 @@ class TunnelInterfaceTest(BasicInterfaceTest.TestCase): self.assertEqual(encapsulation, conf['linkinfo']['info_kind']) self.assertEqual(self.local_v6, conf['linkinfo']['info_data']['local']) self.assertEqual(remote_ip6, conf['linkinfo']['info_data']['remote']) - self.assertEqual(0, conf['linkinfo']['info_data']['ttl']) + self.assertEqual(64, conf['linkinfo']['info_data']['ttl']) self.assertEqual(f'0.0.0.{ip_key}', conf['linkinfo']['info_data']['ikey']) self.assertEqual(f'0.0.0.{ip_key}', conf['linkinfo']['info_data']['okey']) self.assertEqual(erspan_ver, conf['linkinfo']['info_data']['erspan_ver']) -- cgit v1.2.3
