Implementations

impl VxlanOverlay

pub const DEFAULT_FDB_AGE: u64 = 300u64

Default FDB aging timeout: 300 ticks (5 minutes at 1 tick/sec).

pub fn new() -> Self

Create a new VXLAN overlay manager.

pub fn add_tunnel(&mut self, tunnel: VxlanTunnel) -> Result<(), VxlanError>

Add a tunnel.

pub fn remove_tunnel(&mut self, vni: u32) -> Result<(), VxlanError>

Remove a tunnel.

pub fn get_tunnel(&self, vni: u32) -> Option<&VxlanTunnel>

Get a tunnel by VNI.

pub fn encapsulate( &self, vni: u32, inner_frame: &[u8], ) -> Result<Vec<u8>, VxlanError>

Encapsulate a frame in a VXLAN header.

Returns the VXLAN-encapsulated packet (header + original frame).

pub fn decapsulate(&self, packet: &[u8]) -> Result<(u32, Vec<u8>), VxlanError>

Decapsulate a VXLAN packet.

Returns (VNI, inner frame).

pub fn fdb_learn(&mut self, mac: MacAddress, vtep_ip: u32, current_tick: u64)

Learn a MAC address from an incoming frame.

pub fn fdb_add_static(&mut self, mac: MacAddress, vtep_ip: u32)

Add a static FDB entry.

pub fn fdb_lookup(&self, mac: &MacAddress) -> Option<&FdbEntry>

Look up a MAC address in the FDB.

pub fn fdb_age(&mut self, current_tick: u64) -> usize

Remove aged-out FDB entries.

pub fn arp_proxy_add(&mut self, ip: u32, mac: MacAddress, vtep_ip: u32)

Add an ARP proxy entry.

pub fn arp_proxy(&self, target_ip: u32) -> Option<MacAddress>

Respond to an ARP request for a remote container.

Returns the MAC address if we can proxy-respond.

pub fn tunnel_count(&self) -> usize

Get tunnel count.

pub fn fdb_count(&self) -> usize

Get FDB entry count.
