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 --- src/vnet/mfib/mfib_types.api | 35 +++++++++++++++++++++++++++++++++++ 1 file changed, 35 insertions(+) create mode 100644 src/vnet/mfib/mfib_types.api (limited to 'src/vnet/mfib/mfib_types.api') diff --git a/src/vnet/mfib/mfib_types.api b/src/vnet/mfib/mfib_types.api new file mode 100644 index 00000000000..b2ba4329ea5 --- /dev/null +++ b/src/vnet/mfib/mfib_types.api @@ -0,0 +1,35 @@ +/* + * Copyright (c) 2018 Cisco and/or its affiliates. + * Licensed under the Apache License, Version 2.0 (the "License"); + * you may not use this file except in compliance with the License. + * You may obtain a copy of the License at: + * + * http://www.apache.org/licenses/LICENSE-2.0 + * + * Unless required by applicable law or agreed to in writing, software + * distributed under the License is distributed on an "AS IS" BASIS, + * WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. + * See the License for the specific language governing permissions and + * limitations under the License. + */ + +import "vnet/fib/fib_types.api"; +import "vnet/ip/ip_types.api"; + +enum mfib_itf_flags +{ + MFIB_API_ITF_FLAG_NONE = 0, + MFIB_API_ITF_FLAG_NEGATE_SIGNAL = 0x1, + MFIB_API_ITF_FLAG_ACCEPT = 0x2, + MFIB_API_ITF_FLAG_FORWARD = 0x4, + MFIB_API_ITF_FLAG_SIGNAL_PRESENT = 0x8, + MFIB_API_ITF_FLAG_DONT_PRESERVE = 0x10, +}; + +/** \brief mFIB path +*/ +typeonly define mfib_path +{ + vl_api_mfib_itf_flags_t itf_flags; + vl_api_fib_path_t path; +}; -- cgit 1.2.3-korg
