set system sysctl parameter Value validation failed (path will exist after commit)
Open, LowPublic

Description

Hello,

i ran into the following "bug" - i add an bridge interface and want to set a sysctl parameter which is not implemented in vyos directly as option in the same commit, but then getting a validation error, which may break automations... It does need 2 commits currently in order to make it work.

# set interfaces bridge br200 description test
[edit]
# set system sysctl parameter net.ipv4.neigh.br200.retrans_time_ms value 60000




  Invalid value
  Value validation failed
  Set failed

[edit]
# comp
[interfaces bridge]
+ br200 {
+     description "test"
+ }
