At least one Listener MUST be specified. \n An implementation MAY group Listeners by Port and then collapse each group of Listeners into a single Listener if the implementation determines that the Listeners in the group are \"compatible\". An implementation MAY also group together and collapse compatible Listeners belonging to different Gateways. \n For example, an implementation might consider Listeners to be compatible with each other if all of the following conditions are met: \n 1. Either each Listener within the group specifies the \"HTTP\" Protocol or each Listener within the group specifies either the \"HTTPS\" or \"TLS\" Protocol. \n 2. Each Listener within the group specifies a Hostname that is unique within the group. \n 3. As a special case, one Listener within a group may omit Hostname, in which case this Listener matches when no other Listener matches. \n If the implementation does collapse compatible Listeners, the hostname provided in the incoming client request MUST be matched to a Listener to find the correct set of Routes. The incoming hostname MUST be matched using the Hostname field for each Listener in order of most to least specific. That is, exact matches must be processed before wildcard matches. \n If this field specifies multiple Listeners that have the same Port value but are not compatible, the implementation must raise a \"Conflicted\" condition in the Listener status. \n Support: Core"

Note the following deviations from the \"host\" part of the URI as defined in the RFC: \n 1. IP literals are not allowed. 2. The `:` delimiter is not respected because ports are not allowed. \n Hostname can be \"precise\" which is a domain name without the terminating dot of a network host (e.g. \"foo.example.com\") or \"wildcard\", which is a domain name prefixed with a single wildcard label (e.g. \"*.example.com\").

routes:
description: "Routes specifies a schema for associating routes with the Listener using selectors. A Route is a resource capable of servicing a request and allows a cluster operator to expose a cluster resource (i.e. Service) by externally-reachable URL, load-balance traffic and terminate SSL/TLS. Typically, a route is a \"HTTPRoute\" or \"TCPRoute\" in group \"networking.x-k8s.io\", however, an implementation may support other types of resources. \n The Routes selector MUST select a set of objects that are compatible with the application protocol specified in the Protocol field. \n Although a client request may technically match multiple route rules, only one rule may ultimately receive the request. Matching precedence MUST be determined in order of the following criteria: \n * The most specific match. For example, the most specific HTTPRoute match is determined by the longest matching combination of hostname and path. * The oldest Route based on creation timestamp. For example, a Route with a creation timestamp of \"2020-09-08 01:02:03\" is given precedence over a Route with a creation timestamp of \"2020-09-08 01:02:04\". * If everything else is equivalent, the Route appearing first in alphabetical order (namespace/name) should be given precedence. For example, foo/bar is given precedence over foo/baz. \n All valid portions of a Route selected by this field should be supported. Invalid portions of a Route can be ignored (sometimes that will mean the full Route). If a portion of a Route transitions from valid to invalid, support for that portion of the Route should be dropped to ensure consistency. For example, even if a filter specified by a Route is invalid, the rest of the Route should still be supported. \n Support: Core"
