* nhrp, lib, zebra: add/del neighbor entry possible from nhrpPhilippe Guibert2021-04-091-2/+2
| | | | | | | | | a zebra api is extended to offer ability to add or remove neighbor entry from daemon. Also this extension makes possible to add neigh entry, not only between IPs and macs, but also between IPs and NBMA IPs. This API supports configuring ipv6/ipv4 entries with ipv4/ipv6 lladdr.

* zebra: link layer config and notification, implementation in zebraPhilippe Guibert2021-04-091-0/+6
| | | | | | | | | | | | | zebra implements zebra api for configuring link layer information. that can be an arp entry (for ipv4) or ipv6 neighbor discovery entry. This can also be an ipv4/ipv6 entry associated to an underlay ipv4 address, as it is used in gre point to multipoint interfaces. this api will also be used as monitoring. an hash list is instantiated into zebra (this is the vrf bitmap). each client interested in those entries in a specific vrf, will listen for following messages: entries added, removed, or who-has messages.

* zebra: BSD null routes were not being installedDonald Sharp2019-11-211-4/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On BSD systems null routes were not being installed into the kernel. This is because commit 08ea27d1121ef5989cdc54fb178c05a7efc4cd3e introduced a bug where we were attempting to use the wrong prefix afi types and as such we were going down the v6 code path. test27.lab.netdef.org# show ip route Codes: K - kernel route, C - connected, S - static, R - RIP, O - OSPF, I - IS-IS, B - BGP, E - EIGRP, N - NHRP, T - Table, v - VNC, V - VNC-Direct, A - Babel, D - SHARP, F - PBR, f - OpenFabric, > - selected route, * - FIB route, q - queued route, r - rejected route K>* 0.0.0.0/0 [0/0] via 192.168.122.1, 00:00:23 S>* 4.5.6.8/32 [1/0] unreachable (blackhole), 00:00:11 C>* 192.168.122.0/24 [0/1] is directly connected, vtnet0, 00:00:23 test27.lab.netdef.org# exit [ci@test27 ~/frr]$ netstat -rn Routing tables Internet: Destination Gateway Flags Netif Expire default 192.168.122.1 UGS vtnet0 4.5.6.8/32 127.0.0.1 UG1B lo0 127.0.0.1 link#2 UH lo0 192.168.122.0/24 link#1 U vtnet0 192.168.122.108 link#1 UHS lo0 Fixes: #4843 Signed-off-by: Donald Sharp <sharpd@cumulusnetworks.com>

* zebra: Modify code so that dplane is responsible for indicating success/fail ↵Donald Sharp2019-03-271-16/+38
| | | | | | | | | | | | | | | | | of install We have several route types KERNEL and CONNECT that are handled via special case in the code. This was causing a lot of work keeping the two different classes of route types as special(SYSTEM OR NOT). Put the dplane in charge of the code that sets the bits for signalling route install/failure. This greatly simplifies the code calling path and makes all route types be handled exactly the same. Additionaly code that we want to run post data plane install can just work as per normal then, instead of having to know we need to run it when we have a special type of route.
