vrouter running ipv4# arp-announce ARP-ANNOUNCE

ARP-ANNOUNCE values

Description

any

Use any local address, configured on any interface.

avoid-not-in-subnet

Try to avoid local addresses that are not in the target’s subnet for this interface. This mode is useful when target hosts reachable via this interface require the source IP address in ARP requests to be part of their logical network configured on the receiving interface. When we generate the request we will check all our subnets that include the target IP and will preserve the source address if it is from such subnet. If there is no such subnet we select source address according to the rules for level 2, ‘best-local’.

best-local

Always use the best local address for this target. In this mode we ignore the source address in the IP packet and try to select local address that we prefer for talks with the target host. Such local address is selected by looking for primary IP addresses on all our subnets on the outgoing interface that include the target IP address. If no suitable local address is found we select the first local address we have on the outgoing interface or on all other interfaces, with the hope we will receive reply for our request and even sometimes no matter the source IP address we announce.
arp-filter

Allows to have multiple network interfaces on the same subnet, and have the ARPs for each interface be answered based on whether or not the kernel would route a packet from the ARP’d IP out that interface (therefore you must use source based routing for this to work). In other words it allows control of which cards (usually 1) will respond to an arp request.

vrouter running config# vrf <vrf> interface vrrp <vrrp> network-stack ipv4
vrouter running ipv4# arp-filter true|false
arp-ignore

Define different modes for sending replies in response to received ARP requests that resolve local target IP addresses.
