From a3d562afdd96d4c37fe608af99f364e879ee92b6 Mon Sep 17 00:00:00 2001 From: Marek Gradzki Date: Thu, 13 Jul 2017 10:41:27 +0200 Subject: HONEYCOMB-369: configurable BGP peers BGP peer configuration is no longer read from bgp-peer.json file. Netconf/Restconf is can be used instead. BGP peer configuration in HC follows openconfig-extensions model (as in ODL BGP): * http://docs.opendaylight.org/en/stable-boron/user-guide/bgp-user-guide.html#bgp-peering * http://docs.opendaylight.org/en/stable-boron/user-guide/bgp-user-guide.html#bgp-application-peer-and-programmable-rib Change-Id: I91aa6c4fc0923edbacf6cd10abd3957569a4f8c6 Signed-off-by: Marek Gradzki --- .../infra/bgp/neighbors/ProtocolCustomizer.java | 75 ++++++++++++++++++++++ 1 file changed, 75 insertions(+) create mode 100644 infra/northbound/bgp/src/main/java/io/fd/honeycomb/infra/bgp/neighbors/ProtocolCustomizer.java (limited to 'infra/northbound/bgp/src/main/java/io/fd/honeycomb/infra/bgp/neighbors/ProtocolCustomizer.java') diff --git a/infra/northbound/bgp/src/main/java/io/fd/honeycomb/infra/bgp/neighbors/ProtocolCustomizer.java b/infra/northbound/bgp/src/main/java/io/fd/honeycomb/infra/bgp/neighbors/ProtocolCustomizer.java new file mode 100644 index 000000000..7e0dd8f45 --- /dev/null +++ b/infra/northbound/bgp/src/main/java/io/fd/honeycomb/infra/bgp/neighbors/ProtocolCustomizer.java @@ -0,0 +1,75 @@ +/* + * Copyright (c) 2017 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. + */ + +package io.fd.honeycomb.infra.bgp.neighbors; + +import static com.google.common.base.Preconditions.checkArgument; +import static com.google.common.base.Preconditions.checkNotNull; + +import io.fd.honeycomb.translate.spi.write.ListWriterCustomizer; +import io.fd.honeycomb.translate.write.WriteContext; +import io.fd.honeycomb.translate.write.WriteFailedException; +import javax.annotation.Nonnull; +import org.opendaylight.yang.gen.v1.http.openconfig.net.yang.network.instance.rev151018.network.instance.top.network.instances.network.instance.protocols.Protocol; +import org.opendaylight.yang.gen.v1.http.openconfig.net.yang.network.instance.rev151018.network.instance.top.network.instances.network.instance.protocols.ProtocolKey; +import org.opendaylight.yang.gen.v1.http.openconfig.net.yang.policy.types.rev151009.BGP; +import org.opendaylight.yang.gen.v1.http.openconfig.net.yang.policy.types.rev151009.InstallProtocolType; +import org.opendaylight.yangtools.yang.binding.InstanceIdentifier; + +/** + * Dummy customizer for handling network-instance's protocol node required by BGP peer configuration (HC implements the + * same model as ODL BGP). + * + * Ensures that at most one protocol is created. + * + * Update and delete is not supported, because HC does not support runtime BGP server reconfiguration. + */ +final class ProtocolCustomizer implements ListWriterCustomizer { + private final String protocolInstanceName; + + ProtocolCustomizer(@Nonnull final String protocolInstanceName) { + this.protocolInstanceName = checkNotNull(protocolInstanceName, "protocol instance name should not be null"); + } + + @Override + public void writeCurrentAttributes(@Nonnull final InstanceIdentifier id, + @Nonnull final Protocol dataAfter, @Nonnull final WriteContext writeContext) + throws WriteFailedException { + final String protocolName = dataAfter.getName(); + checkArgument(protocolInstanceName.equals(protocolName), + "Only single protocol named %s is supported, but %s was given", protocolInstanceName, protocolName); + + final Class identifier = dataAfter.getIdentifier(); + checkArgument(BGP.class.equals(identifier), + "Only BGP protocol type is supported, but %s was given", identifier); + } + + @Override + public void updateCurrentAttributes(@Nonnull final InstanceIdentifier id, + @Nonnull final Protocol dataBefore, @Nonnull final Protocol dataAfter, + @Nonnull final WriteContext writeContext) throws WriteFailedException { + throw new WriteFailedException.UpdateFailedException(id, dataBefore, dataAfter, + new UnsupportedOperationException("Network instance protocol update is not supported")); + } + + @Override + public void deleteCurrentAttributes(@Nonnull final InstanceIdentifier id, + @Nonnull final Protocol dataBefore, @Nonnull final WriteContext writeContext) + throws WriteFailedException { + throw new WriteFailedException.DeleteFailedException(id, + new UnsupportedOperationException("Network instance protocol delete is not supported")); + } +} -- cgit 1.2.3-korg
