Hello
How do you program in a static arp entry on an interface that is using
family inet unnumbered-address ?
Eg.:
interface ps1 {
unit 2766 {
proxy-arp restricted;
vlan-tags outer 402 inner 1016;
family inet {
unnumbered-address lo0.1;
}
}
}
routing instance internet routing-options {
interface et-0/0/0.2766;
static {
route 192.0.2.11/24 {
qualified-next-hop et-0/0/0.2766;
}
route 198.51.100.22/24 {
qualified-next-hop et-0/0/0.2766;
}
It is not possible to have the juniper router do correct arp in this case.
You can have the 192.0.2.0/24 range working or you can have the
198.51.100.0/24 working using preferred source address but not both. So I
figured I could get away with simply hard coding the arp entry. However
static arp is in the family inet address subtree so can not be specified
here. Seriously ?
