When both IPv4 interface columns and IPv6 interface columns are configured over a
PPP link-layer interface, the router terminates the PPP session only when the PPP
client exceeds the configured maximum number of renegotiation attempts for both
the IPv4 interface and the IPv6 interface.
Example 1—Sets the maximum number of LCP renegotiation attempts to 5
host1(config-if)#ppp max-negotiations lcp 5
Example 2—Sets the maximum number of IPCP renegotiation attempts to 30 (the
default)
host1(config-if)#ppp max-negotiations ipcp
Example 3—Sets the maximum number of LCP, IPCP, and IPv6CP renegotiation
attempts to 15
host1(config-if)#ppp max-negotiations 15
Example 4—Restores the maximum number of LCP, IPCP, and IPv6CP renegotiation
attempts to the default value, 30
host1(config-if)#no ppp max-negotiations
Use the no version to restore the default value, 30 renegotiation attempts.
See ppp max-negotiations.
Use to control the negotiation of the maximum receive unit (MRU).
Specify the number of bytes, in the range 64–65535.
We recommend you coordinate this value with the network administrator on the other
end of the line.
If the value configured for the PPP MRU is greater than the value of the lower-layer
MRU minus the PPP header length, the router logs a warning message and uses the
lesser of the configured MRU value or the lower-layer MRU value minus the PPP header
length to negotiate the local MRU.
If the value configured for the PPP MRU conflicts with a similar value configured for
another protocol, such as the MTU value for PPPoE, the router uses the lesser of the
two values.
Example
host1(config-if)#ppp mru 576
Use the no version to restore the default value, which causes PPP to use the lower-layer
MRU minus the PPP header length as the MRU value.
See ppp mru.
