From 097fa66b986f06281f603767d321ab13ab6c88c3 Mon Sep 17 00:00:00 2001 From: Neale Ranns Date: Tue, 1 May 2018 05:17:55 -0700 Subject: fib: fib api updates 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 Signed-off-by: Ole Troan Signed-off-by: Paul Vinciguerra --- test/test_vxlan.py | 21 +++++++++++++-------- 1 file changed, 13 insertions(+), 8 deletions(-) (limited to 'test/test_vxlan.py') diff --git a/test/test_vxlan.py b/test/test_vxlan.py index aa069dc6e7b..c74efe7d062 100644 --- a/test/test_vxlan.py +++ b/test/test_vxlan.py @@ -10,6 +10,8 @@ from scapy.layers.l2 import Ether, Raw from scapy.layers.inet import IP, UDP from scapy.layers.vxlan import VXLAN from scapy.utils import atol +from vpp_ip_route import VppIpRoute, VppRoutePath +from vpp_ip import INVALID_INDEX class TestVxlan(BridgeDomain, VppTestCase): @@ -84,17 +86,20 @@ class TestVxlan(BridgeDomain, VppTestCase): # Create 10 ucast vxlan tunnels under bd ip_range_start = 10 ip_range_end = ip_range_start + n_ucast_tunnels - next_hop_address = cls.pg0.remote_ip4n - for dest_ip4n in ip4n_range(next_hop_address, ip_range_start, - ip_range_end): + next_hop_address = cls.pg0.remote_ip4 + for dest_ip4 in ip4_range(next_hop_address, ip_range_start, + ip_range_end): # add host route so dest_ip4n will not be resolved - cls.vapi.ip_add_del_route(dst_address=dest_ip4n, - dst_address_length=32, - next_hop_address=next_hop_address) + rip = VppIpRoute(cls, dest_ip4, 32, + [VppRoutePath(next_hop_address, + INVALID_INDEX)], + register=False) + rip.add_vpp_config() + dest_ip4n = socket.inet_pton(socket.AF_INET, dest_ip4) + r = cls.vapi.vxlan_add_del_tunnel(src_address=cls.pg0.local_ip4n, dst_address=dest_ip4n, vni=vni) - cls.vapi.sw_interface_set_l2_bridge(rx_sw_if_index=r.sw_if_index, - bd_id=vni) + cls.vapi.sw_interface_set_l2_bridge(r.sw_if_index, bd_id=vni) @classmethod def add_del_shared_mcast_dst_load(cls, is_add): -- cgit 1.2.3-korg
