2017-09-11FIB table add/delete APINeale Ranns1-2/+64
part 2; - this adds the code to create an IP and MPLS table via the API. - but the enforcement that the table must be created before it is used is still missing, this is so that CSIT can pass. Change-Id: Id124d884ade6cb7da947225200e3bb193454c555 Signed-off-by: Neale Ranns <nranns@cisco.com>
2017-08-15Support proxy ARP on mirrored TAP interfacesNeale Ranns1-0/+64
When VPP has an interface whose address is also applied to a TAP interface on the host, then VPP's TAP interface will be unnumbered to the 'real' interface and do proxy ARP from the host. the curious aspect of this setup is that ARP requests from the host will come from the VPP's own address.

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>
