}

Generic policy key for IPv4 and IPv6.

func (*PolicyKey) Match

func (k *PolicyKey) Match(vrfID uint32, cidr *net.IPNet) bool

Match returns true if the vrfID and destCIDR parameters match the SRv6 policy key.

	DestCIDR types.IPv4 `align:"dst_cidr"`
}

type PolicyKey6

type PolicyKey6 struct {
	// PrefixLen is full 32 bits of VRF ID + DestCIDR's mask bits
	PrefixLen uint32 `align:"lpm"`

	VRFID    uint32     `align:"vrf_id"`
	DestCIDR types.IPv6 `align:"dst_cidr"`
}

type PolicyValue

type PolicyValue struct {
	SID types.IPv6

type SIDValue struct {
	VRFID uint32
}

type SRv6PolicyIterateCallback

type SRv6PolicyIterateCallback func(*PolicyKey, *PolicyValue)

SRv6PolicyIterateCallback represents the signature of the callback function expected by the IterateWithCallback method, which in turn is used to iterate all the keys/values of an SRv6 policy map.

type SRv6SIDIterateCallback

type SRv6SIDIterateCallback func(*SIDKey, *SIDValue)

SRv6SIDIterateCallback represents the signature of the callback function expected by the IterateWithCallback method, which in turn is used to iterate all the keys/values of an SRv6 SID map.

type SRv6StateIterateCallback

type SRv6StateIterateCallback func(*StateKey, *StateValue)

SRv6StateIterateCallback represents the signature of the callback function expected by the IterateWithCallback method, which in turn is used to iterate all the keys/values of an SRv6 state map.

type SRv6VRFIterateCallback

type SRv6VRFIterateCallback func(*VRFKey, *VRFValue)

SRv6VRFIterateCallback represents the signature of the callback function expected by the IterateWithCallback method, which in turn is used to iterate all the keys/values of an SRv6 policy map.
