2020-07-02vrrp: fix feature declaration for v6 accept-modeMatthew Smith1-1/+1
Type: fix The v6 accept mode input feature was being declared with the node added to ip4-multicast instead of ip6-multicast. Add to the correct arc. Change-Id: I08f6e5e7dde84a37687fa0af750a7a16fe537ea6 Signed-off-by: Matthew Smith <mgsmith@netgate.com>
2020-06-27vrrp: backup processes priority 255 advertisementMatthew Smith1-0/+348
Type: fix When accept mode is enabled, a backup VR will configure the VR virtual addresses locally and respond to packets sent to those addresses. This did not work when the primary VR is the address owner and sends advertisements using the virtual address as the source address. It also did not work when NAT was configured on the interface with the virtual address as the NAT pool address. In both cases, advertisements from other VRs would arrive and be dropped because they appeared to be spoofed - the source address would be an address that is configured as an interface address on the instance receiving it. When accept mode is enabled for a VR and the VR enters the master state, add an input feature on ip[46]-multicast for the interface which looks for VRRP advertisements, figures out whether they are for a VR which is configured with accept mode and is in the master state and kicks them straight to the VRRP nodes to avoid dropping them.
