37-294
Command Mode:
BGP route mode and address-family mode
Usage Guide:
As the negotiation is the default, it can be disabled with this configuration when it is known that the
partner BGP version is old which don’t support capability negotiation.
Example:
Last addition capability negotiation will not be realized in the connection by configuring as follows.
Switch(config-router)#neighbor 10.1.1.64 dont-capability-negotiate
37.54 neighbor ebgp-multihop
Command:
neighbor {<ip-address>|<TAG>} ebgp-multihop [<1-255>]
no neighbor {<ip-address>|<TAG>} ebgp-multihop [<1-255>]
Function:
Configures the EBGP neighbors can existing in different segment as well as its hop count (TTL).
The “no neighbor {<ip-address>|<TAG>} ebgp-multihop [<1-255>]” set that the EBGP neighbors
must be in the same segment.
Parameter:
<ip-address>: Neighbor IP address.
<TAG>: Name of the peer group.
<1-255>: Allowed hop count.
Default:
Must be in the same segment.
Command Mode:
BGP route mode and address-family mode
Usage Guide:
Without this command, EBGP peers are required to be in the same segment and after this
command is configured, peer addresses may from different segments. The allowed hop count can
be configured and will be 255 if not.
Example:
Three device 10.1.1.64(AS100) and 11.1.1.120(AS300) connected respectively to the two interface
10.1.1.66 and 10.1.1.100 of another device. IGP accessibilities of 10.1.1.64 and 11.1.1.120 on both
side routes are ensured through static configuration. The neighbor relationship is established only
after both side are configured as follows:
on 10.1.1.64
