Method Detail

parseMpReach

MpReachNlri parseMpReach(io.netty.buffer.ByteBuf buffer,
                         @Nullable PeerSpecificParserConstraint constraint)
                  throws BGPParsingException

Decode MP REACH NLRI Attribute.

Parameters:

buffer - Input buffer.

constraint - Peer specific constraint.

Returns:

Parsed reach NLRI.

Throws:

BGPParsingException

parseMpUnreach

MpUnreachNlri parseMpUnreach(io.netty.buffer.ByteBuf buffer,
                             @Nullable PeerSpecificParserConstraint constraint)
                      throws BGPParsingException

Decode MP REACH NLRI Attribute.

Parameters:

buffer - Input buffer.

constraint - Peer specific constraint.

Returns:

Parsed unreach NLRI.

Throws:

BGPParsingException

serializeMpReach

void serializeMpReach(MpReachNlri mpReachNlri,
                      io.netty.buffer.ByteBuf byteAggregator)

Encode BGP MP REACH NLRI Attribute.

Parameters:

mpReachNlri - Input reach NLRI.

byteAggregator - Output buffer.

serializeMpUnReach

void serializeMpUnReach(MpUnreachNlri mpUnreachNlri,
                        io.netty.buffer.ByteBuf byteAggregator)

Encode BGP MP UNREACH NLRI Attribute.

Parameters:

mpUnreachNlri - Input unreach NLRI.

byteAggregator - Output buffer.

getSerializers

Iterable<NlriSerializer> getSerializers()

Get all available NLRI encoders.

Returns:

Iterable of NLRI serializers.

convertMpReachToMpUnReach

Optional<MpUnreachNlri> convertMpReachToMpUnReach(MpReachNlri mpReachNlri,
                                                  @Nullable MpUnreachNlri mpUnreachNlri)

Convert MP_REACH attribute to MP_UNREACH attribute and merge it with original one if it exists.

The default implementation rejects the conversion.

Parameters:

mpReachNlri - MP_REACH attribute to be converted

mpUnreachNlri - original MP_UNREACH attribute

Returns:

resulting MP_UNREACH attribute after conversion
