This class implements a recipe that configures a simple IP6GRE tunnel between two hosts.

The actual test machinery is implemented in the
BaseEnrtRecipe
class.The test wide configuration is implemented in the
BaseTunnelRecipe
class.- configure_underlying_network(config: EnrtConfiguration) tuple[RemoteDevice, RemoteDevice]
The underlying network for the tunnel consists of the Ethernet devices on the matched hosts.
- create_tunnel(config: EnrtConfiguration, tunnel_endpoints: tuple[RemoteDevice, RemoteDevice]) tuple[RemoteDevice, RemoteDevice]
The IP6GRE tunnel devices are configured with IPv4 and IPv6 addresses of individual networks. Routes are configured accordingly.
- generate_ping_endpoints(config)
The ping endpoints for this recipe are simply the tunnel endpoints
Returned as:
[PingEndpoints(self.matched.host1.gre6_tunnel, self.matched.host2.gre6_tunnel)]
- get_packet_assert_config(ping_config)
The packet assert test configuration contains filter for ip6 protocol and grep patterns to match the ICMP or ICMP6 echo requests encapsulated by IP6GRE.
