From 5a029892e97a7a5ef4450237412eaa6ce29aeb39 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.
