ADSL timing drop problem in Linux

Today's new Redhat 5.4 Enterprise Edition, configure a bit of PPPoE, ready to drive on the books to travel, but I am surprised that the connection between the PPP Non-stop, a new terminal, has been ping, found that the network every minute or so automatically fell once, and then automatically reconnect, Look at the message log and find the following, repeated:

Immediately on the Internet search, found that there are a number of people on the Internet, or modify the content of the/etc/ppp/options, or modify the content of/etc/ppp/pppoe-server-options, I also in these two documents wasted a lot of time, Testing a long time, the network situation remains the same, and then a thought, the usual modification of IP settings and so on the network card set, try to vi/etc/sysconfig/network-scripts/ifcfg-ppp0 inside made a modification, the original document is as follows:

Userctl=no

Bootproto=dialup

Name=dslppp0

Device=ppp0

Type=xdsl

Onboot=no

Pidfile=/var/run/pppoe-adsl.pid

Firewall=none

Ping=.

Pppoe_timeout=80

Lcp_failure=3

Lcp_interval=20

clampmss=1412

Connect_poll=6

Connect_timeout=60

Defroute=yes

Synchronous=no

Eth=eth0

Provider=dslppp0

user=46804

Peerdns=no

Demand=no

Ipv6init=no

Persist=no

The two places in this file were modified:

Lcp_failure=30

Lcp_interval=30

So far, there has been a continuous drop in the situation, in fact, the above two statements of any one of the values, modified to solve the problem.
