2019-06-18fib: fib api updatesNeale Ranns1-172/+109
Enhance the route add/del APIs to take a set of paths rather than just one. Most unicast routing protocols calcualte all the available paths in one run of the algorithm so updating all the paths at once is beneficial for the client. two knobs control the behaviour: is_multipath - if set the the set of paths passed will be added to those that already exist, otherwise the set will replace them. is_add - add or remove the set is_add=0, is_multipath=1 and an empty set, results in deleting the route. It is also considerably faster to add multiple paths at once, than one at a time: vat# ip_add_del_route 1.1.1.1/32 count 100000 multipath via 10.10.10.11 100000 routes in .572240 secs, 174751.80 routes/sec vat# ip_add_del_route 1.1.1.1/32 count 100000 multipath via 10.10.10.12 100000 routes in .528383 secs, 189256.54 routes/sec vat# ip_add_del_route 1.1.1.1/32 count 100000 multipath via 10.10.10.13 100000 routes in .757131 secs, 132077.52 routes/sec vat# ip_add_del_route 1.1.1.1/32 count 100000 multipath via 10.10.10.14 100000 routes in .878317 secs, 113854.12 routes/sec vat# ip_route_add_del 1.1.1.1/32 count 100000 multipath via 10.10.10.11 via 10.10.10.12 via 10.10.10.13 via 10.10.10.14 100000 routes in .900212 secs, 111084.93 routes/sec Change-Id: I416b93f7684745099c1adb0b33edac58c9339c1a Signed-off-by: Neale Ranns <neale.ranns@cisco.com> Signed-off-by: Ole Troan <ot@cisco.com> Signed-off-by: Paul Vinciguerra <pvinci@vinciconsulting.com>

2018-05-11Periodic scan and probe of IP neighbors to maintain neighbor poolsJohn Lo1-1/+25
Scan IPv4 and IPv6 neigbor pool entries once a minute to keep them up to date. The neighbor of an entry is probed if its time-stamp is older than 1 minute. If the neighbor respond, its time-stamp will be updated. If there is no response from a neighbor, its entry will be deleted when the time-stamp of the entry become more than 4 minutes old. Static neighbor entries are not probed nor deleted. Implemented CLI and API to enable and disable priodic scan of IPv4, IPv6 or both types of IP neighbors. CLI is "ip scan-neighbor" and API is "ip_scan_neighbor_enable_disable". Other IP neighbor scan parameters can also be changed from their defaults via the CLI/API.

A UDP-encap object that particiapates in the FIB graph and contributes DPO to teh output chain. It thereofre resembles a tunnel but without the interface. FIB paths (and henace routes) can then be created to egress through the UDP-encap. Said routes can have MPLS labels, hence this also allows MPLSoUPD. Encap is uni-directional. For decap, one still registers with the UDP port dispatcher. Change-Id: I23bd345523b20789a1de1b02022ea1148ca50797 Signed-off-by: Neale Ranns <nranns@cisco.com>

2017-10-05Distributed Virtual Router SupportNeale Ranns1-0/+1
A distributed virtual router works by attmpeting to switch a packet, but on failing to find a local consumer (i.e. the packet is destined to a locally attached host) then the packet is sent unmodified 'upstream' to where the rest of the 'distributed' router is present. When L3 switching a packet this means the L2 header must not be modifed. This patch adds a 'l2-bridge' object to the L3 FIB which re-injects packets from the L3 path back into the L2 path - use with extreme caution.

It's not true primary/backup function because the FIB must converge before the lower preference paths are used.
