2017-05-17VPP-719: Accept ARP replies from VRRP hw addrMatthew Smith1-0/+75
Check whether an ARP src hw addr starts with 00:00:5e:00:01 before rejecting due to a mismatch between ARP src hw addr and ethernet frame src addr. Change-Id: Ia3ecd5d6dba34876aca8d90bc622a0a1397e48fb Signed-off-by: Matthew Smith <mgsmith@netgate.com>
2017-05-17ARP learning fixes (VPP-843)Neale Ranns1-8/+30
learn ARP peers if, 1) it's a reply to a local address, 2) we are sending a response to a request. send proxy ARP responses only in the interface the request was sent. Change-Id: I22b949c65122824233076492b7dd537daca07bc2 Signed-off-by: Neale Ranns <nranns@cisco.com>
2017-03-17Attached hostsNeale Ranns1-11/+165
allow this config to function: set int ip address loop0 169.254.1.1/32 (the default GW address for attached hosts) set int unnumbered af_packet0 use loop0 ('enable' IP on the host interface) ip route add 192.168.1.1/32 via af_packet0 (where to find the host) repeat for each host and host interface. Inter-host communication is throught the /32 routes. To allow this: 1 - attached host routes have the ATTACHED flag set, so the ARP code accepts then as legitimate sources 2 - unnumbered interfaces inherit the source address from the IP interface Change-Id: Ib66c5f0e848c528f79372813adc3a0c11b50717f Signed-off-by: Neale Ranns <nranns@cisco.com>
