ZXR10 T600/T1200 User Manual (IPv6 Volume)
To configure BGP4+ aggregation advertisement, perform the fol-
lowing steps.
St-
ep Command Function
1
ZXR10(config)#
router bgp < as-number > This enters BGP route
configuration mode.
2
ZXR10(config-router)#
aggregate-address
< ip-addr > / < mask >[ as-set ][ summary-only ]
This creates an aggregation
policy in the BGP routing
table.
3
ZXR10(config-router)#
bgp aggregate-nexthop-check This implements route
aggregation only when the
next hop strictly matches with
MED.
Result: BGP4+ aggregation advertisement has been configured.
Configuring EBGP Multihop
To configure EBGP multihop, perform the following steps.
St-
ep Command Function
1
ZXR10(config)#
router bgp < as-number > This enters BGP route
configuration mode.
2
ZXR10(config-router)#
neighbor [< ipv4-address >|< i
pv6-address >|< peer-group-name >] ebgp-multihop
[ ttl < value >]
This configures to establish
EBGP neighborhood over
non-direct connect networks.
The range of TTL is 1–255.
The default is 8.
Result: EBGP multihop has been configured.
Example
Usually, EBGP neighborhood is established on the direct-connect
interfaces of two routers.
To establish EBGP neighborhood on
non-direct connect interfaces, the command neighbor ebgp-m
ultihop shall be used to perform EBGP multihop configuration, as
well as proper IGP or static route configuration to enable intercom-
munication between non-direct connect neighbors.T
This example describes how to configure EBGP multihop.
As shown in Figure 6 , router R1 in AS 100 needs to establish
neighborhood with a non-directly connected interface whose id is
180.225.11.1 on R2 in AS300.
