Function TestSubnetRouterMultiNetwork

integration/route_test.go:1842–1991

TestSubnetRouterMultiNetwork is an evolution of the subnet router test. This test will set up multiple docker networks and use two isolated tailscale clients and a service available in one of the networks to validate that a subnet router is working as expected.
